Title:
COLOR FILM SUBSTRATE AND PREPARATION METHOD THEREFOR, AND LIQUID CRYSTAL DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2024/098274
Kind Code:
A1
Abstract:
A color film substrate, comprising a base substrate, a black matrix layer, a color resist layer, a protective layer and a support column layer which are sequentially stacked. The black matrix layer is provided with light-transmitting windows arranged in an array. The color resist layer covers the light-transmitting windows. The support column layer is provided with support columns. The color film substrate comprises a plurality of different partitions. In at least some of the partitions, the color resist layer is provided with partition grooves located between light-transmitting window rows and exposing the black matrix layer. The orthographic projection of each support column on the base substrate at least partially overlaps with the orthographic projection of each partition groove on the base substrate. The widths of the partition grooves are different in at least two partitions, and the width of each partition groove is the size of the partition groove in the column direction. The color film substrate can improve the uniformity of the support columns.
