PURPOSE: A colored photo-sensitive resin composition is provided to increase contrast ratio and solvent resistance without the exfoliation of patterns during a development process. CONSTITUTION: A colored photo-sensitive resin composition includes a coloring agent, an alkali soluble resin, a photo-polymerizable compound, a photo-polymerization initiator, and a solvent. The coloring agent includes a diketopyrrolopyrrole-based dye represented by chemical formula 1. The alkali soluble resin includes a structural unit represented by chemical formula 2. In the chemical formulas, A1 and A2 are respectively -Cl, -CN, -CF3, -NO2, -COY, -COOY, -N(CH3)2, -N(CH2CH3)2, and -NHCH3; Y is hydrogen or a C1-15 alkyl group; R1 is a functional group of chemical formula 1-a; and R1 and R2 are respectively hydrogen or a methyl group. |
