BLACK PHOTOSENSITIVE RESIN COMPOSITION FOR BLACK MATRIX, BLACK MATRIX USING THE SAME AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a black photosensitive resin composition for a black matrix capable of forming a black matrix having satisfactory adhesive power, a sufficient light extinction density and a low reflectance and free from protrusions due to overlapping with colored pixels without dissolving the black photosensitive resin composition in frame parts even in the case of over-development in formation and to provide a black matrix and a method for producing the matrix.;SOLUTION: In the black photosensitive resin composition consisting essentially of a hydroxystyrene-base high molecular compound resin which is crosslinked under an acid, a crosslinker, a photo-acid generator and grafted carbon black, the high molecular compound resin is a copolymer comprising 39 mol% units of formula (1), 49 mol% units of formula (2) and 12 mol% units of formula (3).;COPYRIGHT: (C)2003,JPO
