Pigment red 177 or the like is used in combination as a coloring pigment. However, in such a pigment composition, there is a case where the reproduction of the red reproduction field of the above CRT standard is difficult in itself, and it is not good enough to obtain a red pixel having high contrast. In contrast, in Patent Document 5, it is disclosed by C. I. Pigment Red 254 is the main pigment, with C. I. Pigment Red 242 is used in combination with a coloring pigment to achieve improved color properties, however, in such a pigment composition, it is still not good enough to obtain a red pixel having high contrast. Further, in Patent Documents 6 to 8, it is disclosed that C is used. I. Pigment Red 2 5 4 and C. I·Pigment Orange 3 8 is used in combination. However, in such a pigment combination, it is not good enough to obtain a red pixel having high contrast, and there is also a case where reproduction of the red reproduction field of the above C R T standard itself is difficult. Due to the above background, there is an urgent need to develop a colored composition capable of reproducing a dark phase close to a CRT and capable of forming a red pixel having high contrast.

Preferably, it is an amount of 10 to 40% by mass. Color Filter The coloring composition of the present invention is suitable for forming red pixels in the red reproduction field which can reproduce the above CRT standard. Specifically, it is suitable for forming a CIE chromaticity coordinate measured by a C light source measured at a 2 degree field of view at 0. 61 S X S 0. 67,0. 31 S y S 0. 35 range of red pixels, especially falling in 〇. 63 S xS 0_67’ 0. 32S 0. 34 range of red pixels. The color filter of the present invention has a red pixel formed of the colored composition of the present invention. As a method of forming a color filter, first, it is known that a coating film of a color ray-sensitive composition is formed on a substrate or a substrate on which a light-shielding layer of a predetermined pattern is formed in advance, and a ray is irradiated through a reticle having a predetermined pattern.

Specifically, first, on the surface of the substrate, a light-shielding layer which is to be formed into a pixel portion is formed as needed, and then a dispersion of the red pigment of the present invention having a radiation sensitivity is applied on the substrate by coating -26-201003148. After the liquid composition of the composition, 'prebaking is performed to evaporate the solvent to form a coating film. Next, the coating film was exposed through a photomask, and developed with an alkali developing solution to dissolve and remove the unexposed portion of the coating film, followed by post-baking to form a pixel array in which a red pixel pattern was arranged in a predetermined layout. Then, 'liquid composition of each coloring composition in which green or blue pigment is dispersed' is applied, and coating, prebaking, exposure, development, and post-baking of each liquid composition are performed in the same manner as above, and red is sequentially formed on the same substrate. A pixel array and a blue pixel array are used to produce a color filter in which pixel arrays of three primary colors of red, green, and blue are disposed on a substrate. However, in the present invention, the order in which the pixels of the respective colors are formed is not limited to the above order. Examples of the substrate used in forming the pixel include glass, sand, polycarbonate, polyester, aromatic polyamide, polyamidimide, and polyimide. Further, these substrates may be subjected to a chemical treatment such as a decane coupling agent, a plasma treatment, an ion plating, a sputtering, a gas phase reaction method, or a vacuum deposition, as appropriate.

The coating method is particularly preferably a spin coating method. The thickness of the coating is usually 0. 1 to 10/zm, preferably 0. 2~8. 0// m’ is especially good. 2 to 6, 0/zm. As the ray used for forming the pixel, for example, a visible light -27 - 201003148 line, an ultraviolet ray, a far ultraviolet ray, an electron beam, an X ray or the like can be used, and a ray in the range of 190 to 450 nm is preferable. The exposure amount of the rays 'is usually 1 〇 1 〇〇〇〇 J/m 2 . When the coloring composition of the present invention is used, an exposure amount of 800 I/m 2 or less and an exposure amount of 600 I/m 2 or less can form an excellent solvent resistance. Further, as the above alkali developing solution, for example, sodium carbonate, sodium, potassium hydroxide, tetramethylammonium hydroxide, choline or 1,8-diaza [5. 4·0]-7-undecene, 1,5-diazabicyclo[4. 3. 0]-5-pinene and other solutions. For example, an appropriate amount of methanol, a water-soluble organic solvent, a surfactant, or the like may be added to the alkali developer. Further, after alkali development, water washing 8 is carried out as a development treatment method, and a rinsing development method, a spray scouring (immersion) development method, a coating method (liquid method), or the like can be employed. The developing conditions are preferably 5 to 300 seconds under development. Further, as a second method of forming a color filter, a method of producing pixels of respective colors by an inkjet method in Japanese Patent Laid-Open Publication No. Hei. No. Hei. The color filter 'of the present invention thus produced can reproduce a dark phase with a CRT and has a high contrast'. Therefore, it is very expensive for a liquid crystal display device having a wide reproduction field represented by TV. Color liquid crystal display element The color liquid crystal display element of the present invention has a color wavelength invention of the present invention or even a normal method such as a hydroxyl alcohol such as oxyhydroxide, and a color furnace light -28-201003148 which is open to the outside of Japan at a normal temperature. The color liquid crystal display element of the present invention can take an appropriate configuration. For example, a color filter may be formed on a substrate other than the driving substrate on which the thin film transistor (TFT) is provided, and the driving substrate and the substrate on which the color filter is formed may face the liquid crystal layer, and A substrate in which a color filter is formed on the surface of the driving substrate on which the thin film transistor (TFT) is provided and a substrate on which an ITO (tin-doped indium oxide) electrode is formed may be employed, and the liquid crystal layer may be opposed to each other. . The latter structure can significantly increase the aperture ratio and has the advantage of being able to produce a bright, high-definition liquid crystal display element.

As can be seen from Tables 1 to 4, if CI Pigment Red 177 and (:·Ι.Pigment Red 24 2 or CI Pigment Orange 38 are used as the colorant, a dark phase close to the CRT can be reproduced, and high contrast can be obtained. In contrast, it can be seen that CI Pigment Red 25 4 and CI Pigment Red 177 are used as colorants, and if a hue close to CRT is reproduced, the contrast is low (Comparative Examples 1 and 7), even if further coloring is performed using a yellow pigment, contrast Also not good enough, and the stimulating enthalpy (Y) also decreased (Comparative Examples 2, 3, 8, and 9). In addition, it is understood that when CI Pigment Red 254 and CI Pigment Red 2 42 or CI Pigment Orange 38 are used as a coloring agent, The stimulating enthalpy (γ) is high, but if CI Pigment Red 254 is used as the main pigment, the contrast is low (Comparative Examples 4, 5, and 10), and if CI Pigment Red 242 or CI Pigment Orange 38 is used as the main pigment, the contrast is not good enough. At the same time, it is difficult to reproduce the hue close to the CRT itself (Comparative Example 6, 1 1 is more surprisingly 'Pixel pattern formed by the colored composition of the present invention' and coloring using CI Pigment Red 254 which was mainly used before. Composition Compared to the pixel pattern further understood more excellent solvent resistance. [] None drawings briefly described. The main element symbol square DESCRIPTION te -39-
