Description
Technical field
The present invention relates to color (image) display technique in the machine that color liquid crystal display arrangement etc. uses color filter.
Background technology
In the color liquid crystal display arrangement etc., adopt color filter display color (image).Color filter generally makes by the painted transparent fine pattern (being called as pixel) that forms three looks on opaque substrates such as transparency carriers such as glass or silicon respectively.Aforementioned three looks in most cases adopt red (R), green (G) and blue (B) these three primary colors.
In this liquid crystal indicator, the color filter that utilizes the three primary colors pixel is to being undertaken painted by the light across the opposed a pair of polaroid of liquid crystal, reveal various colors (pixel) again, specifically, from all pixels, make till the situation (showing black) that light begins light is seen through with Min. with the situation (whitening) that sees through to greatest extent, reproduce various colors.In order to reduce power consumption, the brightness of the color filter when requiring to improve this liquid crystal indicator whitening in addition, also requires to improve the repeatability of color under the prerequisite that brightness is descended.Therefore, for example the resin combination of the versicolor pixel that forms color filter various improvement have been carried out.For example, the blue color filter of having developed the values Y (brightness) when fully having increased whitening is with feeling the radioactivity composition, if adopt this blue composition, then the reproduction range of color increases to some extent, even pigment concentration increases, the brightness of liquid crystal indicator descends also can be prevented (for example, opening 2001-147315 communique (～the 3 page of right hurdle of the 2nd row, the 2nd page of left hurdle the 14th row) with reference to the Jap.P. spy).In addition, also developed the green color filter coating composition of the transmittance that has improved the visible light scope, if adopt this green composite, then can improve the color rendition and the brightness (for example, with reference to Japanese patent laid-open 10-160928 communique (the 2nd page of left hurdle the 2nd row～right hurdle the 21st row)) of liquid crystal indicator.In addition, also develop mean grain size with pigment and be resized to color filter composition in the specialized range, if employing said composition, then can improve transmittance and contrast (for example, with reference to Japanese patent laid-open 9-197118 communique (～the 3 page of left hurdle of the 2nd row, the 2nd page of left hurdle the 35th row)).
In addition, also improve at the color filter this respect, for example, open in the 2001-272523 communique (～the 3 page of left hurdle of the 2nd row, the 2nd page of left hurdle the 9th row) the Jap.P. spy, the transmitance of red pixel, blue pixel and green pixel and the color filter of excitation have been proposed to improve, if adopt this color filter, then can realize low power consumption and high color reprodubility.In addition, open in the 2001-116918 communique (the 2nd page of left hurdle the 2nd row～right hurdle the 27th row) the Jap.P. spy, proposed the transmitance of the transmitance of red pixel and green pixel is adjusted to color filter in the specialized range, the color temperature of (during whitening) in the time of can improving printing opacity.
Summary of the invention
But, to liquid crystal indicator require characteristic to be not limited in above-mentioned whitening the time brightness (or color temperature of whitening) and color reprodubility.That is also be very important less to the deviation that shows the colourity the black process, from whitening.This requires characteristic to estimate with the display characteristic of any point from whitening to apparent process of deceiving, in the past, the technology of the characteristic of the technology of the structure by utilizing relevant liquid crystal display cells, relevant driving circuit waits and realizes fully, for example, must utilize the adjustment of polarized light film and the small adjustment of each color pixel.But, utilize the adjustment of polarized light film that the contrast of LCD degree is descended, in addition, the small adjustment of carrying out each color pixel is extremely difficult.

Show coloured material that the photosensitive polymer combination group (red colour system photosensitive polymer combination, green are that photosensitive polymer combination and blueness are the photosensitive polymer combination group) of above-mentioned characteristic (1)～(8) can be by adjusting at least a photosensitive polymer combination etc., make it with remaining photosensitive polymer combination formation best of breed and obtain.
Specifically, for example, make photosensitive polymer combination film forming of all kinds, obtain resin combination film of all kinds, clamp the resin combination film with a pair of polarization plate respectively, respectively under the polarizing axis of polarization plate situation and orthogonal crossing situation parallel to each other, respectively to the tristimulus values (X of CIE (International Commission on Illumination) 1931 color specification systems of resin combination film of all kinds, Y Z) measures, by following formula try to achieve the whitening coordinate (u '

In the system film step, the color filter of photosensitive polymer combination that makes the photosensitive polymer combination of photosensitive polymer combination with look 1, look 2 and look 3 obtains resin combination film of all kinds with the photosensitive polymer combination film forming of all kinds of photosensitive polymer combination group.
In the determination step, clamp the resin combination film with a pair of polarization plate respectively, respectively under the polarizing axis of polarization plate situation and orthogonal crossing situation parallel to each other, respectively to the tristimulus values (X of CIE (International Commission on Illumination) 1931 color specification systems of resin combination film of all kinds, Y, Z) Y in measures.

At last in set-up procedure, for make chromaticity coordinate (colourity) as the redness of look 1, as the chromaticity coordinate (colourity) of the green of look 2 and as chromaticity coordinate (colourity) no change of the blueness of look 3, the balance of the contrast that each resin combination is intermembranous increases and carries out the adjustment of the composition of any photosensitive polymer combination at least.Each chromaticity coordinate and characteristic (8) are determined equally.
The adjustment of composition specifically is meant the adjustment of the coloured material in the photosensitive polymer combination, appends filler pigment in photosensitive polymer combination, adds the one-tenth that sends fluorescence and grade in photosensitive polymer combination.
More specifically, for example, adjust the coloured material of at least a kind of photosensitive polymer combination Y as required for the characteristic that manifests characteristic (2)～(8) for after manifesting above-mentioned characteristic (1) and adjusting the coloured material of at least a kind of photosensitive polymer combination X.As the aforementioned photosensitive polymer combination X that adjusts object and photosensitive polymer combination Y can be identical also can be different.
The method of adjustment of concrete coloured material can exemplify multiple, and it is not particularly limited, and for example, what recommended is the adjustment (modulation) of the coloured material that carries out for the balance that obtains the contrast between photosensitive polymer combination.If obtained the balance of contrast, then can show above-mentioned characteristic (1)～(8).
Under the situation of the balance that obtains contrast, can adopt the whole bag of tricks according to the kind of coloured material.For example, under the situation that coloured material is made of coloring pigment at least, can obtain the balance of contrast by adjusting the mean grain size of this coloring pigment; Also can obtain the balance of contrast by combination coloring pigment and filler pigment (non-coloring pigment); Except also making it, coloring pigment contains the balance that the composition that sends fluorescence also can obtain contrast.In addition, under the situation that coloured material only is made of illuminating colour, can obtain the balance of contrast by it being contained send the composition of fluorescence.Can adopt the adjustment of aforementioned mean grain size, and with filler pigment, and with sending in the composition of fluorescence any, also can multiple appropriate combination use.Below, the whole bag of tricks is described in detail.
[adjustment of mean grain size]
Improve in the photosensitive polymer combination group in the past that contrast is a purpose doing one's utmost, mean grain size of all kinds is less, but by using the bigger coloring pigment of mean grain size, can obtain the balance of contrast.Specifically, for example corresponding to the photosensitive polymer combination of the highest film of contrast, increase the mean grain size of its coloring pigment.Like this, because this photosensitive polymer combination becomes the contrast of film formed resin combination film to descend, so can obtain the balance of each intermembranous contrast.If mean grain size is excessive, the contrast of the integral body when then forming color filter can obviously descend, so in the best simultaneously scope of the contrast of the integral body when being preferably in the balance that can realize the contrast of (between pixel) between resin combination and forming color filter mean grain size is adjusted.
On the other hand, from improving the contrast T of color filter integral body
A11The viewpoint of (aftermentioned) considers, preferably reduces the mean grain size corresponding to the coloring pigment of the photosensitive polymer combination of the minimum film of contrast.Like this, the contrast that this photosensitive polymer combination becomes film formed photosensitive polymer combination film can be improved, the balance of each intermembranous contrast can be obtained thus.
The adjustment of average primary particle diameter, fairly simple is that the different coloring pigment of mixing mean grain size [also can be color index (C.I.; Color index) the identical coloring pigment of numbering].Mean grain size also can according to whether realize in composition characteristic (1)～(8) each, have or not and do suitably to set with the filler pigment and the number etc. of coloring pigment that sends composition, the mixing of fluorescence, for example, under the situation of 2 kinds of coloring pigment mixing, most applications is that mixing mean grain size 50～200nm (better is 53～150nm, being more preferably 55～100nm) coloring pigment and mean grain size 100～300nm (better is 105～200nm, is more preferably 10～150nm) coloring pigment.
Mean grain size is represented the mean value that minor axis is long and major axis is long of particle.Specifically, from the photo that the infiltration type electron microscope is taken, select 50 pigment particles at random, obtain the long mean value and the long mean value of major axis of minor axis of these selected particles, calculate this average minor axis mean value long and that average major axis is long again and just can know mean grain size.
[and using filler pigment (non-coloring pigment)]
To do one's utmost to improve in the photosensitive polymer combination group in the past that contrast is a purpose, and with the filler pigment that contrast is descended, but by and can obtain the balance of contrast with filler pigment.Specifically, for example corresponding to adding filler pigment in the photosensitive polymer combination of the highest film of contrast.Like this, because this photosensitive polymer combination becomes the contrast of film formed resin combination film to descend, so can obtain the balance of each intermembranous contrast.At this moment, in order to have given play to the effect of filler pigment, preferably comprise coloring pigment in the photosensitive polymer combination of interpolation filler pigment.
The particle diameter of filler pigment can be selected from the particle diameter that causes Mie scattering, for example, fusion is gone under the situation of green system: compositions, its particle diameter can be from (better being more than the 150nm more than about 100nm, be more preferably more than the 200nm), select in the scope of 400nm following (better be below the 300nm, it is following to be more preferably 280nm).
The blended amount of filler pigment can according to whether realize in composition characteristic (1)～(8) each, whether adjust mean grain size, whether and with sending the composition of fluorescence and the particle diameter of filler pigment etc. do suitably to set.In most cases, when the solid formation component in resin combination was 100 mass parts, the blended amount of filler pigment was for example selected in the scope of (better being more than 0.015%, to be more preferably more than 0.02%) more than 0.01%.If the blended amount of filler pigment is too much, the contrast of the integral body when then forming color filter obviously descends, so set the upper limit of filler pigment amount in the best simultaneously scope of the contrast of the integral body when being preferably in the balance that can realize the contrast of (between pixel) between resin combination and forming color filter.When the solid formation component in the resin combination was 100 mass parts, the blended amount of filler pigment in most cases for example (better was below 0.08%, is more preferably below 0.05%) below 0.1% about.
As filler pigment, can use known various filler pigment, for example, can adopt the pigment (aluminium oxide, titania etc.) of the non-coloring in the inorganic pigment described later.
[sending the composition of fluorescence]
To do one's utmost to improve in the photosensitive polymer combination group in the past that contrast is a purpose, use the composition that sends fluorescence, but by also can obtain the balance of contrast with the composition that sends fluorescence.Specifically, for example corresponding to adding the composition that sends fluorescence in the photosensitive polymer combination of the highest film of contrast.Like this, because this photosensitive polymer combination becomes the contrast of film formed resin combination film to descend, so can obtain the balance of each intermembranous contrast.

It the results are shown in table 4～6, is shown in the Fig. 2 as the partial enlarged drawing of CIE 1976 USC chromatic diagrams simultaneously.Among Fig. 2, the chromaticity coordinate during white marking (, ◇, △, zero, ☆) expression whitening, the blacking mark (■, ◆, ▲, ●, ★) chromaticity coordinate when expression shows black.
Can find out obviously that from table 1～table 6 in the photosensitive polymer combination group of experimental example 4, the contrast of green based resin composition balance too high and red colour system resin combination and blue based resin composition is short of.The chromaticity coordinate of chromaticity coordinate when specifically, form showing black during from whitening has the combination of bigger displacement to purple direction (direction that intersects with the black body locus approximate vertical).If adopt such resin combination group to make the liquid crystal color filter, even then adjust the structure of liquid crystal display cells and the characteristic of driving circuit etc., the color adjustment that also is difficult to carry out liquid crystal display.
Corresponding to this, in the photosensitive polymer combination group of experimental example 1,, can guarantee that red colour system, green system, blueness are the appropriate balance between each resin combination by in green based resin composition, mixing the pigment (C.I. pigment yellow 185) that sends fluorescence.In addition, in the photosensitive polymer combination group of experimental example 2,, can guarantee that red colour system, green system, blueness are the appropriate balance between each resin combination by mixing the bigger pigment of mean grain size.In the photosensitive polymer combination group of experimental example 3, can guarantee that by mixing filler pigment red colour system, green system, blueness are the appropriate balance between each resin combination.Like this, among the embodiment 1～3, the contrast of comparing the easily unusual high green based resin composition film of contrast with other color descends, and can guarantee the appropriate balance of the contrast that the resin combination of 3 looks intermembranous like this, can manifest above-mentioned various characteristics.
Among the embodiment 5,, make the contrast T of green based resin composition film by mixing the pigment that sends fluorescence
GreenDescend, reduce the mean grain size of the coloring pigment of red colour system resin combination film simultaneously, make and compare contrast with other color and be the contrast T of minimum red colour system resin combination film easily
RedIncrease.Therefore, when guaranteeing of all kinds the appropriate balance of contrast, can improve whole contrast T

Specifically, in the experimental example 1～3,5, when form showing black and the approaching combination of chromaticity coordinate during whitening, also formed the combination that the correlated colour temperature that shows black raises.In addition, form the combination of brightness (the average Y value) rising of whitening.In the experimental example 1, form from whitening to the apparent black chromaticity coordinate and the combination of black body locus almost parallel.Therefore,, then can guarantee suitable balance in the color filter stage if make the liquid crystal color filter with this resin combination group, so that the color adjustment of liquid crystal display.
