PURPOSE: A colored photo-sensitive resin composition and a compound functioning as dyes are provided to facilitate a color filter for a light emitting diode type backlight liquid display device by reducing the change of contrast and transparency before and after a thermal curing process. CONSTITUTION: A colored photo-sensitive resin composition includes the mixture of dyes and pigments as a coloring agent. The dyes include one or more compound represented by chemical formula I. In chemical formula 1, R1, R2, and R4 are respectively hydrogen elements, C1 to C10 alkyl groups, phenyl group substituted or non-substituted with one or more halogen elements, and phthalimidyl groups; R3 is a hydroxyl group, a C1 to C5 alkoxy group, or -O-C(=O)-X3; X1 is -S(=O)_2-, -C(=O)-, -O-, -C(CH_3)_2-, -CH_2-, or a coupling group; X2 and X3 are respectively C1 to C5 alkyl groups; and n is the integer of 1 to 5. |
