The invention relates to a colored photosensitive resin composition, a color filter having the same and an image display device. The colored photosensitive resin composition is characterized by containing a non-reactive alkali-soluble resin and a photopolymerization initiator (A), and the photopolymerization initiator (A) contains a photopolymerization initiator (a1) containing two oxime groups inone molecule, so that the shape of a pattern can be realized in the form of a taper after the post-baking process in the color filter process. A problem in the manufacturing process does not occur, and it is possible to prevent a hole from being formed in the formed pattern.
