Examples of the radiation used in forming the pixel and/or the black matrix include a xenon lamp, a halogen lamp, a tungsten lamp, a high-intensity ultra-high pressure mercury lamp, a metal halide lamp, a medium-pressure mercury lamp, and a low-pressure mercury-family The light sheet is chrome in the above film, but it can also be coated with the polyamine, and can be plated or splashed by the method of using the method of spinning. -49- 201211695 YAG laser, but with wavelength at

XeCl excimer laser, nitrogen ray ί 90 ~ 450nm range of light source or argon ion laser and other laser sources are preferred. The exposure amount of the radiant radiation is generally l0~1 〇, and 〇〇〇j/m2 is preferably 袅Λ in the above test solution.氢氧化钠 Sodium hydroxide, hydrogen for 1 h, and sage is an aqueous solution such as sodium carbonate, hydrazine bicyclo-[5.4.0 M_11 fluorene, choline, 1,8-diene, and the like.丫 double % - [4.3. 〇] - 5 - 壬 : 2: In the developer solution, an appropriate amount of water-based organic solvent or surfactant can be added. Further, the development method can be carried out by the method of "exposure processing", "expanding and developing method", "dip immersion", and immersion: preferably at room temperature, 5 to 300 seconds. #显示衫条件 The conditions of post-cultivation are usually between 180~28〇t, 1〇~6〇 minutes. The film thickness of the pixel formed in this manner is preferably 1.0 to 3.0 μm. In addition, in the second method of producing a color calender sheet, it can be obtained by an inkjet method, which is disclosed in Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. Pixel I method for each color. In this method, first, a partition wall which functions as a light blocking function is formed on the surface of the substrate. Next, in the formed partition walls, for example, a coloring composition of the present invention in which a red coloring agent is dispersed is discharged by an ink jet device: a large composition, followed by prebaking to evaporate the solvent. Then, the two children's film is treated as -50-201211695, and after hardening, it is hardened by post-baking to form a red pattern. Next, each of the colored compositions of green or blue is used, and the pixel pattern of the green pixel image is sequentially formed on the same substrate. Thereby, a color filter having a pixel pattern of red, green, and primary colors disposed on the substrate can be obtained. However, the order in which the pixels of the respective colors are formed is not limited to the above. Further, the partition wall has a function of not only a light-shielding function but also a coloring composition of each color extruded in the division, and the film thickness is thicker than that of the black matrix used in the above-described first method, and the partition wall is usually black. The method or condition for the 'pre- or post-culture of the substrate or radiation used to form the color filter to form the color filter is the same as the first. In this way, the height of the film thickness wall of the pixel formed by the ink jet method is the same. On the pixel pattern thus obtained, a transparent conductive film is formed by sputtering after being formed as needed. Forming a transparent conductive material may further form a spacer to form a color filter. The spacer is formed using a radiation-sensitive composition, but may be formed as a spacer (black spacer). In this case, a color-sensing radiation-linear composition of a divided coloring agent may be used, but the object of the present invention may also be suitably used for the formation of a black spacer such as the color filter of the present invention. Since the film is extremely bright and extremely high, it is extremely useful in color liquid crystal display elements, color image sensor element sensors, organic EL display elements, electronic papers, etc. < After the film is separated from the light source, the method is usually separated from the black film coloring group, and the color is -51 - 201211695. The child E is a piece of light, and the color of the color element is clearly visible. This liquid is prepared in color. The element can be expressed in the form of a paper, and the electric component and the component of the component are shown in the display. The color liquid crystal display element having the color filter of the present invention can be suitably constructed. For example, a color filter may be formed on a substrate different from a substrate for driving a thin film transistor (TFT), and a substrate having a driving substrate and a color filter may be opposed to each other via a liquid crystal layer, and further It is also possible to adopt a structure in which a substrate on which a color filter is formed on a surface of a substrate for driving a thin film transistor (TFT) and a substrate on which an IT〇 (tin-doped indium oxide) electrode is formed are opposed to each other via a liquid crystal layer. The latter structure allows the aperture ratio to be remarkably improved, and has the advantage of providing a bright and high-definition liquid crystal display element. The color liquid crystal display element having the color filter of the present invention may be provided with a backlight unit using a white LED as a light source, except for a CCFL (CFL) lamp. In the case of white LED, for example, a combination of a red LED and a green LED and a blue LED can be used to obtain a white light white LED by color mixing, and a blue LED and a red LED and a green light emitting phosphor can be combined by color mixing. A white LED with white light is obtained, a blue LED is combined with a red illuminating phosphor and a green illuminating illuminant, and a white LED is obtained by color mixing, and a white light is obtained by mixing the blue LED and the YAG phosphor. White LED, blue LE〇 combined with orange illuminating phosphor and green illuminating phosphor to obtain white light white LED by mixing color, ultraviolet LED and red luminescent phosphor and green luminescent phosphor and blue A color light-emitting phosphor is combined to obtain a white light white LED or the like by color mixing. -52- 201211695 In the color liquid crystal display element having the color filter of the present invention, TN (Twisted Nematic) type, STN (Super Twisted Nematic) type, IPS (In-Planes Switching) type, VA (Vertical) can be used.

A suitable liquid crystal mode such as Alignment type or OCB (Optically Compensated Birefringence) type. Further, the organic EL display element having the color filter of the present invention may have a suitable structure, and for example, it may be a structure disclosed in Japanese Laid-Open Patent Publication No. Hei No. Hei.
