PHOTO-SENSITIVE RESIN COMPOSITION FOR A COLOR FILTER AND THE COLOR FILTER USING THE SAME CAPABLE OF IMPROVING THE HEAT RESISTANCE CHARACTERISTIC AND THE CHEMICAL RESISTANCE CHARACTERISTIC OF THE COMPOSITION

摘要

PURPOSE: A photo-sensitive resin composition for a color filter and the color filter using the same are provided to improve aperture ratio and the contrast ratio of the color filter.;CONSTITUTION: A photo-sensitive resin composition for a color filter includes a copolymer, an acryl-based photo-polymerizable monomer, a photo-polymerization initiator, a pigment, and a solvent. The copolymer includes a structural unit which is represented by chemical formula 1. In chemical formula 1, R1 and R2 are respectively H or substituted or non-substituted C1 to c20 alkyl group; and Y is selected from a group including structures represented by chemical formulas 2 to 4. In chemical formulas 2 to 4, R3 to R6 are respectively H or substituted or non-substituted C1 to C20 alkyl group; and X1 to X5 are respectively H, halogen, hydroxyl group, substituted or non-substituted amino group, substituted or non-substituted C1 to C20 alkyl group, allyl group, and C6 to C30 aryl group.;COPYRIGHT KIPO 2012
