In the present invention, the colored composition can be prepared by an appropriate method and can be prepared by mixing the above respective components. The preparation method of the coloring composition may be exemplified by pulverizing and mixing a coloring agent together with a part of the adhesive resin in a solvent in the presence of a dispersing agent, for example, using bead milling or roll milling. The coloring agent dispersion liquid is dispersed, and a method of mixing a polyfunctional monomer, an adhesive resin, or the like with a solvent further added as needed is added to the colorant dispersion.

The dispersing aid may, for example, be a pigment derivative, and specific examples thereof include a copper phthalocyanine, a diketopyrrolopyrrole, a sulfonic acid derivative of quinoline yellow, and the like. Next, a method of manufacturing the color filter of the present invention will be described. For the method of producing a color filter, the first method is as follows. First, a light shielding layer (black matrix) is formed on the surface of the substrate as needed to divide the region where the pixel is formed. Next, the substrate is coated on the substrate to be selected from (1) C. I. Pigmentred242, (2) C. I. Pigment red 177 and C. I.  At least one of the red colorants in the group consisting of pigment red 254 is subjected to pre-baking to form a coating film by dispersing the liquid composition of the colored composition. Then, the coating film was exposed through a photomask, and developed using an alkali developing solution to dissolve and remove the unexposed portion of the coating film. Then, by post-baking, a red pixel pattern of the pixel array is formed in a predetermined arrangement. Next, the liquid composition of each of the colored compositions dispersed by using a green or blue coloring agent is applied, pre-baked, exposed, developed, and post-baked in the same manner as described above, in sequence. A green -27-201142373 color halogen array and a blue pixel array were formed on the same substrate. Thereby, a color filter in which the pixel arrays of the three primary colors of red, green and blue are arranged on the substrate is prepared. However, in the present invention, the order in which the pixels of the respective colors are formed is not limited to the above. Further, the black matrix can be formed by using a metal film such as chromium which is formed by sputtering or vapor deposition to form a desired pattern by photolithographic imaging, but it can also be dispersed by using a black coloring agent. The composition is formed in the same manner as in the case of forming the above-described pixels. The film thickness of the black matrix composed of the metal thin film is usually 0. 1~0. On the other hand, the film black matrix formed using the black composition has a film thickness of about ιμηη. Examples of the substrate used in forming the pixel include glass, enamel, polycarbonate, polyester, aromatic polyamide, polyamidoimine, and polyimine. Further, it is also possible to apply an appropriate pretreatment such as drug treatment, plasma treatment, ion plating, sputtering, gas phase reaction method, vacuum vapor deposition or the like using a decane coupling agent or the like to the substrate. When the liquid composition of the coloring composition is applied onto the substrate, an appropriate coating method such as a spray method, a roll coating method, a rotary coating method (spin coating method), a slit die coating method, or a bar coating method may be employed. However, it is particularly preferred to spin coating or slot die coating. The prebaking is usually carried out by combining drying under reduced pressure with heating and drying. Drying under reduced pressure is usually carried out at 0 · 1 to 1 To rr. Further, the conditions of heat drying are usually about 70 to 110 ° C for about 1 to 10 minutes. For the radiation used in forming the color filter, for example, -28-201142373 may be exemplified by a xenon lamp, a halogen lamp, a tungsten lamp, a high pressure mercury lamp, an ultrahigh pressure mercury lamp, a metal halide lamp, a medium pressure mercury lamp, A light source such as a low-pressure mercury lamp or a laser source such as an argon ion laser, a YAG laser, a XeCl excimer laser, or a nitrogen laser, but preferably has a wavelength in the range of 19 to 4 5 Onm. radiation. The exposure amount of the radiation is preferably 10 0 to 1 0, 0 0 0 J / m 2 . Further, in the case of an alkali developer, for example, sodium carbonate, sodium hydroxide, potassium hydroxide, tetramethylammonium hydroxide, choline, 1,8-diguanidine bicyclo-[5. 4. 0]-7-undecene, 1,5-diguanidine bicyclo-[4. 3. An aqueous solution of 0]-5-pinene or the like. A water-soluble organic solvent such as methanol or ethanol or a surfactant may be added to the alkali developer in an appropriate amount. Further, it is usually washed with water after alkali development. For the development treatment method, a shower development method, a spray development method, a dip (dip) development method, a paddle development method, or the like can be employed. The developing conditions are preferably 5 to 300 seconds at normal temperature. The conditions for post-baking are usually 180~2 800 t, 20~40 minutes. The film thickness of the pixel thus formed is usually 0. 5~5. Ομπι, preferably 1 · 0 ~ 3. 0 μ m. Further, as a second method for producing a color filter, a method of producing each color pixel by an ink jet method is known. In this method, first, a partition wall having a shading function is formed on the surface of the substrate. Then, the inkjet device will be contained in the formed partition wall to be selected from (1) C. I.  Pigment red 242, (2) C. I.  Pigment red 177 and C. I.  Pigment red 254 Structure -29- 201142373 At least one of the red colorants in the group is sprayed with the liquid composition of the dispersed color composition, and then prebaked to evaporate the solvent. Then, after exposing the coating film as needed, it is hardened by post-baking to form a red pixel pattern. Next, a liquid composition of each coloring composition dispersed by using a green or blue coloring agent is used, and The green pixel pattern and the blue pixel pattern are sequentially formed on the same substrate in the same manner as described above. Thereby, a color filter in which the pixel patterns of the three primary colors of red, green and blue are arranged on the substrate is prepared. However, in the present invention, the order in which the respective color pixels are formed is not limited to the above. Further, since the partition walls are not only a light-shielding function, but also have a function of preventing color mixing of the coloring compositions which are ejected in the divided regions, the film thickness is thicker than that of the black matrix used in the first method. The film thickness is usually 1 to 3 μm. Therefore, the partition wall usually uses a black composition to form a substrate or a radiation source used in forming the color filter, and the method or condition of prebaking or post-baking is the same as the first method described above. . In this way, the film thickness of the pixel formed by the ink jet method is the same as the film thickness of the partition wall. On the color filter thus obtained, a protective film is formed as needed, and a transparent conductive film is formed by sputtering. On the transparent conductive film, a spacer is further formed as needed. The transparent conductive film may, for example, be a NESA film made of tin oxide (registered trademark of PPG, USA), an ITO film made of indium oxide-tin oxide, or an IZO film made of indium oxide-zinc oxide. In addition, the inorganic film formed of the thermosetting resin composition -30-201142373, the SiNx film, the SiOx film or the like is usually formed of a radiation-sensitive composition.
