Abstract
A liquid crystal display device includes an array substrate, a color filter substrate, and a liquid crystal layer provided between the array substrate and the color filter substrate. 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. 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.

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.
A method of manufacturing a color filter substrate of a liquid crystal display device, including:
- Step 1, forming a color filter unit pattern on a substrate in the form of matrix;
- and
- Step 2, forming a black matrix pattern on the substrate after the Step 1, the black matrix pattern protruding from the substrate and including a lateral structure and a longitudinal structure that are formed integrally to enclose pixels,
- wherein grooves are provided on the black matrix pattern, and the grooves are provided on the lateral structure of the black matrix pattern and/or the longitudinal structure of the black matrix pattern.
