Problems solved by technology

The existing technology to solve it is usually a method of adjusting the acid value and molecular weight of the binder resin or the acid value of the binder resin and the composition, but its application range is limited, and when the acid value is too high, the adhesion is not enough , become the cause of surface defects, in addition, even residues remaining on metal oxide films and silicon nitride films have limitations that are difficult to solve

Abstract

The invention relates to a color photosensitive resin composition, a color filter comprising the color photosensitive resin composition, and a display device. The color photosensitive resin composition comprises a colorant, an alkali-soluble resin, a photopolymerization compound, a photopolymerization initiator and a solvent, and is characterized in that the photopolymerization initiator comprises an oxime ester compound and the solvent comprises hydroxy-4-methyl-2-pentanone.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition, a color filter and a display device including the colored photosensitive resin composition. Background technique [0002] Since color filters are widely used in imaging elements, liquid crystal display devices (LCDs), and the like, their range of applications is rapidly expanding. A color filter used in a color liquid crystal display device or an imaging device, etc. is usually applied by spin coating, and a colored photosensitive resin composition containing pigments corresponding to various colors such as red, green, and blue is uniformly coated on the pattern to form a black color filter. After being placed on the substrate of the matrix, the coating film formed by heating and drying (hereinafter also referred to as "pre-baking") is exposed and developed, and further heat-cured (hereinafter also referred to as "post-baking") is repeated for each color as required. Baking")...
