Colored photosensitive resin composition, color filter and image display device

The embodiment of the invention provides a colored photosensitive resin composition, a color filter and an image display device. The colored photosensitive resin composition comprises a colorant, an alkali-soluble resin, a photopolymerizable compound, a photopolymerization initiator and a solvent, and the colorant comprises C.I. Pigment green 36, C.I. Pigment yellow 185 and C.I. Pigment blue 16. The alkali-soluble resin comprises a repeating unit derived from a blocked isocyanate-based compound represented by chemical formula 1 and a repeating unit derived from a hydroxyl group-containing (meth) acrylate-based compound represented by chemical formula 2, and a thin film manufactured from the colored photosensitive resin composition has a transmittance of 50% or more at a wavelength of 530 nm and a full width at half maximum of less than 45 nm. 本发明的实施例提供着色感光性树脂组合物、滤色器和图像显示装置。着色感光性树脂组合物包含着色剂、碱溶性树脂、光聚合性化合物、光聚合引发剂和溶剂，着色剂包含C.I.颜料绿36、C.I.颜料黄185和C.I.颜料蓝16，碱溶性树脂包含来源于化学式1所表示的封端异氰酸酯系化合物的重复单元和来源于化学式2所表示的含羟基(甲基)丙烯酸酯系化合物的重
