Patent ID: 8264658

Claim:
A liquid crystal display device, including: an array substrate; a color filter substrate; and a liquid crystal layer provided between the array substrate and the color filter substrate, wherein the color filter substrate includes: a substrate; a plurality of color filter units provided on the substrate in the form of matrix; and a black matrix pattern including a lateral structure and a longitudinal structure that are formed integrally to enclose pixals, wherein the black matrix pattern is provided between the array substrate and the color filter substrate and partially contacts with the array substrate to block light and maintain a cell thickness between the array substrate and the color filter substrate, and wherein grooves are provided on the black matrix pattern, the grooves are provided on the lateral structure of the black matrix pattern and/or the longitudinal structure of the black matrix pattern, and the depth of the grooves are set to a depth, with which liquid crystal material can freely flow from one pixel to another pixel and the block matrix pattern is capable of blocking light.
