PHOTOSENSITIVE COLORED RESIN COMPOSITION FOR COLOR FILTER, COLOR FILTER, LIQUID CRYSTAL DISPLAY DEVICE, AND ORGANIC ELECTROLUMINESCENT DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide a photosensitive colored resin composition for a color filter, the composition having a high light-shielding property and high volume resistance and showing a good tapered shape.

SOLUTION: The photosensitive colored resin composition for a color filter comprises an alkali-soluble resin, a photopolymerization initiator, a coloring material and a dispersant, in which the coloring material includes a black pigment and an organic color pigment excluding a black pigment, the content of the black pigment is 20 to 95 wt.% of the sum of the black pigment and the organic color pigment excluding a black pigment, and the alkali-soluble resin comprises an alkali-soluble resin (A-1) and/or an alkali-soluble resin (A-2). The alkali-soluble resin (A-1) is obtained by allowing a reaction product of a specified epoxy compound (a) and an unsaturated group-containing carboxylic acid to react with a polybasic acid and/or its anhydride. The alkali-soluble resin (A-2) is obtained by allowing a reaction product of an epoxy compound expressed by formula (1) and an unsaturated group-containing carboxylic acid to react with a polyhydric alcohol and a polybasic acid and/or its anhydride.
