Problems solved by technology

[0004] However, when a dye is used as an auxiliary pigment, there will be a problem that the degree of curing is insufficient, and the pattern formed during the development process using an alkaline developer will peel off. It is necessary to improve the phenomenon of color migration that reduces the transmittance of the green or red pixel part due to diffusion.

Abstract

The present invention provides a colored photosensitive resin composition, a color filter by using the colored photosensitive resin composition and an image display device. The colored photosensitiveresin composition comprises a coloring agent, an alkali-soluble resin, a photopolymerizable compound, a photopolymerization initiator, and a solvent, and the coloring agent contains a pigment and a dye, and the dye contains a ruthenium having a COOM or a COO group in the molecule. The above-mentioned alkali-soluble resin contains a repeating unit containing a dicyclopentyl group, and the photopolymerization initiator contains an oxime ester compound which generates a methyl radical by light irradiation, and the solvent contains an organic solvent having a hydroxyl group in the molecule. The colored photosensitive resin composition of the present invention is excellent in transmittance, and has no residue or pattern peeling when the color filter is produced, and does not lower the transmittance of adjacent pixel portions, and is excellent in storage stability.

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 color filter that is excellent in transmittance, has no residue and pattern peeling off of the manufactured color filter, and does not transmit light from adjacent pixel portions. A colored photosensitive resin composition having a reduced rate and excellent storage stability, 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 display devices, and the like, and the range of applications thereof is rapidly expanding. A color filter is generally produced by uniformly coating a colored photosensitive resin composition containing colorants corresponding to red, green, and blue colors on a substrate having a black matrix pattern by...
