COLORED PHOTO-SENSITIVE RESIN COMPOSITION, A COLOR FILTER, AND A LIQUID CRYSTAL DISPLAY DEVICE INCLUDING THE SAME CAPABLE OF REDUCING THE CHANGE OF COLOR AFTER A HIGH TEMPERATURE-BASED PROCESS BY INCLUDING THERMAL CROSS-LINKING ALICYCLIC EPOXY RESIN

摘要

PURPOSE: A colored photo-sensitive resin composition, a color filter, and a liquid crystal display device including the same are provided to improve the sensitivity and the quality of the color filter based on few amount of exposure and to prevent the generation of residues on a substrate after a developing process.;CONSTITUTION: A colored photo-sensitive resin composition includes thermal cross-linking alicyclic epoxy resin, a coloring material containing C.I. pigment green 58, binder resin, a poly-polymerizable compound, a photo-polymerization initiator, and a solvent. The thermal cross-linking alicyclic epoxy resin is copolymer based on the copolymerization of a compound which is represented by chemical formula 1. In chemical formula 1, the R1 is hydrogen element or C1 to C4 alkyl group, and the alkyl group is capable of being substituted with hydroxyl group; and the R2 is C1 to C20 aliphatic or aromatic hydrogen carbon with/without a single bond or a hetero element.;COPYRIGHT KIPO 2012
