Abstract

The invention discloses a color photoresist composition. The color photoresist composition comprises 5-10% of pigment dispersion liquid, 5%-8% of a binder resin, 0.3%-0.8% of a photoinitiator, and 5%-8% of a porphyrin compound represented by the following formula (I), wherein M represents a central coordination metal of the porphyrin compound, is selected from an alkaline earth element or a subgroup element, or M represents two hydrogen atoms; R1 represents an alkyl group having 1 to 20 C atoms, or an alkoxy group having 1 to 20 C atoms; or R1 represents an optionally substituted aryl group; or R1 represents hydrogen.

Description

technical field [0001] The present invention relates to a color photoresist composition, in particular to a color photoresist composition containing porphyrin compounds. Background technique [0002] Color filter (Color Filter, CF) is an important part of LCD. When the light passes through the red (R), green (G), and blue (B) pixels on the CF, it will show three colors of RGB. After mixing these three colors, various colors to be displayed can be formed, so , which can make the picture of the liquid crystal display colorful. The red, green, and blue pixels are formed by color photoresists, and the chemical components of the color photoresists mainly include pigments, binder resins, dyes, photoinitiators, solvents, and additives. [0003] The two parameters x and y of CIE1931 color coordinates are usually used to describe the color characteristics of light, also known as the color point, with x on the horizontal axis and y on the vertical axis. This color point accurately r...
