/ Night crystal display mode is mostly used in computers, color TVs, mobile phones, and photography. The liquid crystal image display element uses a color filter formed with respective color pixels and a liquid crystal having a shutter function to image the surface. /, person, shirt color filter is usually first on the surface of a transparent substrate such as glass, plastic sheet, etc. to form a black matrix (black matrix) with a strip (stiP) or mosaic (mosaic), etc. (1) Then, three or more different colors of red, #, and blue are sequentially formed on the opening, and the completion is performed. Here, the function of the black matrix is to control the mixing between the colors and to prevent Light leakage achieves the effect of improving contrast. Therefore, it is based on the requirement of high light-shielding; the film uses a vapor-deposited film such as chrome with high opacity. However, due to its complicated forming steps and high price, it has recently been used. Development imaging method containing pigment and photosensitive resin (phGtQlithQgraphy, pigment method) ο The pigment method described above is a combination of a black pigment such as carbon black or a plurality of pigments in a black form. 2066-9284-PP Ahddub 5 200831618 Further, in order to obtain the ruthenium shielding property, it is necessary to greatly increase the content I of the pigment itself, but when the pigment concentration is higher, the developability, the resolution, the adhesion, the stability, etc. The characteristics are lowered, and the improvement of the light-shielding property is limited. On the other hand, the film forming the color filter is also required to be thinned, and the pigment is required to be high in concentration, which is further promoted. As a result of the dispersion stability and fluidity reduction, in order to solve the above problems, the following schemes have been proposed: carbon black having a specific surface area of ll 〇 m 2 /g or less, pH of 2 to 9, and having a basic function A photosensitive resin composed of a polymer dispersing agent composed of a polyester or a polyether (for example, JP-A No. 〇-〇829〇8); an average primary particle diameter of 20 to 30 nm and a DBP oil absorption amount i4 are used.碳ml/i〇〇g or less, ?11 is 2.5~4 carbon black, and amine value 1~1〇〇111 finds 11/§ organic compound dispersant composed of carbon black dispersion (for example, special JP-A-2004-292672. The pigment dispersion as described above has a characteristic that dispersion stability and fluidity are excellent even when the ruthenium pigment concentration is used. However, recently, in a color liquid crystal display device, the color is vivid. Degree and sales The increase is proportional to the increase, so the market is also very strong in anticipation of improving the vividness of color. Therefore, due to the poor formation of color filters, light films or special matrix patterns, color leaks and other colors may be damaged. The cause of the brightness has become a very important research topic. To form a black matrix by the development imaging method, first, a black matrix photoresist composition is applied onto a substrate, and then, by having a predetermined pattern. The photomask is exposed to ultraviolet light' and the coating film of the exposed portion is hardened. Connected to 2〇66-9284~PF; Ahddub 6 200831618, the developer is used to remove the unexposed film of the Nine Nine Injury, which is formed as described above. A black matrix of a given pattern. At this time, it is boasted that in order to obtain a good pattern, it is necessary to require the light pdan composition to have good pattern reproducibility. For example, at the end of the development, it is necessary to achieve the unexposed "cutting τ / and the developing residue", and the exposed portion has sufficient fine line reproducibility; 5 law 'M and the north form a sharp edge pattern, etc. 8. However, 'as a black matrix' is not only highly opaque, but also highly opaque to ultraviolet light. Therefore, even in the exposed portion, even if the surface of the coating is hardened, the edge near the substrate is still unreachable due to ultraviolet rays. The original state before the hardening. Then the 'unhardened residual portion is slowly eroded and thinned by the developer, and finally the exposed portion is also completely removed, and the black matrix disappears. The complete removal of the above In the above-mentioned unexposed portion, when the exposed portion is thinned and the length of time between the functions defined as the black matrix cannot be obtained, it is called "development margin" (Development Utitude). In the lesser case, since the unexposed part is removed, the exposure σ卩 will be fine or disappeared immediately. Therefore, it is difficult to find out the timing of stopping the development. Especially the above is high. The photoresist composition having a pigment concentration is likely to be high in the unhardened ratio in the exposure 4, so that sufficient development wideness cannot be obtained. Therefore, the unexposed portion cannot be completely removed, and the exposed portion is thinned. However, it is not possible to obtain a problem that is in conformity with the prescribed functions and the like in terms of engineering management.

After mixing the average sentence, the filter is used to filter the filter to obtain the actual column 12, and the black matrix for the comparative examples 1 to 3 is used. The pigment disperses the photoresist composition. (Evaluation Test) (Dispersion Stability) • Each of the black matrix pigments of Examples 1 to 12 and Comparative Examples 1 to 3 was dispersed and formed, and the respective blacks of Example 12 and Comparative Example 3 were obtained. The matrix material dispersion resist composition was sampled and placed in a glass bottle to be sealed, and after storage at room temperature for 7 days, the state was evaluated according to the following evaluation criteria. To A: no thickening and sedimentation 'B: thickening and sedimentation with a slight sway to restore the original degree C: material with strong shaking and will not return to the original state and sinking matter (developability of photoresist pattern) • Using a photoresist coater, the pigment dispersion resist compositions of the black matrix of Examples 1 to 12 and Comparative Examples ～3 were applied onto a glass substrate so as to form an i (four) film thickness, and 10 (pre-bake for 3 minutes under rc. Thereafter, a reticle with a grid pattern of a line width of 20:80 in area ratio of hardened portion to unhardened portion is used, and a high-pressure mercury lamp is used to accumulate light amount of 400 mJ/in uv.
