Light sensitive composition for black matrix, substrate for color filter, and liquid crystal display |
摘要 |
A light-sensitive composition for forming a black matrix comprises (a) a photopolymerizable unsaturated compound, (b) a photopolymerization initiator, (c) a binder and (d) a pigment, wherein the amount of monovalent metallic cations present in the pigment as impurities is not more than 5 ppm; a black matrix is formed from the composition; a color filter substrate comprises a transparent substrate and a color filter formed thereon, wherein it further comprises the foregoing black matrix formed thereon; and a liquid crystal display device comprises an array substrate provided thereon with display electrodes and switching elements, a color filter substrate, common electrodes and a liquid crystal injected in the space between the array substrate and the color filter substrate, wherein it further comprises the foregoing black matrix formed on the switching elements or on the color filter substrate. The black matrix shows desired shading properties without impairing the quality of driving elements even when it is directly formed thereon. Moreover, the surface area of the black matrix can be minimized and the opening of the picture elements can be increased.
