Abstract

The present invention provides a colored photosensitive resin composition containing an alkali-soluble resin, a photopolymerizable compound, and a photopolymerization initiator, a color filter formed using the same, and an image display device including the color filter. , a colorant and a solvent, the above-mentioned alkali-soluble resin includes an alkali-soluble resin polymerized by N-benzylmaleimide, and the above-mentioned photopolymerization initiator includes an oxime ester fluorene-based photopolymerization initiator of a specific structure. The colored photosensitive resin composition of the present invention has a fast developing speed, is excellent in adhesion, sensitivity, and reliability, and can minimize outgassing.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition, a color filter, and an image display device. More specifically, it relates to a colored photosensitive resin composition that has a high developing speed, excellent adhesion, sensitivity, and reliability, and can minimize outgassing A product, a color filter formed using the colored photosensitive resin composition, and an image display device including the color filter. Background technique [0002] Color filters are widely used in imaging elements, liquid crystal displays (LCDs), and the like, and their application range is rapidly expanding. A color filter is usually produced by uniformly coating a colored photosensitive resin composition containing pigments corresponding to red, green, and blue colors on a substrate having a pattern of a black matrix, and then heating and drying the formed coating. The film is exposed, developed, and the operation of heating and curing is...
