Composite white pigment, photoresist material containing same and application of composite white pigment

The invention relates to the field of liquid crystal display, in particular to a composite white pigment and a photoresist material. The composite white pigment comprises an inner core prepared from a non-white pigment, and an outer layer prepared from a white pigment, wherein the photoresist material provided by the invention is prepared from the following components in parts by weight: 5-15 parts of a photosensitizer, 5-15 parts of a dispersing agent, 50-80 parts of a solvent and 5-15 parts of a composite white pigment. Through a double-layer structure design with different colors in inner layer and outer layer, the defects of the original ordinary pure white pigment on a light absorption surface are improved with the nonwhite inner core; improvement of the light absorption properties of the traditional white photoresist material is facilitated; the absorption rate of the white color on the light can be increased; the screening capacity of the photoresist is improved; the color can be relatively uniform; the material can be ideally applied to a one-glass-solution (OGS) frame material; a few of manufacture procedures of a white lithography process can be reduced; and the OD value can be effectively increased.
