Abstract

The invention provides a liquid crystal display panel, which comprises a thin film transistor array substrate, a color filter substrate and a plurality of first spacers; the thin film transistor array substrate and the color filter substrate are oppositely arranged; the thin film transistor array substrate comprises a first substrate, a thin film transistor array and a color filter layer; the thin film transistor array and the color filter layer are arranged on the surface, adjacent to the color filter substrate, of the first substrate; the color filter substrate comprises a second substrate, a black matrix layer and a first alignment film; the black matrix layer and the first alignment film are arranged on the surface, adjacent to the thin film transistor array substrate, of the second substrate in sequence; grooves are formed in the black matrix layer; first through holes are formed in the first alignment film; each first through hole is formed by corresponding to the corresponding groove; each first spacer comprises a first end and a second end; each first end is contained in the corresponding groove through the corresponding first through hole, and each second end is arranged by corresponding to the color filter layer. The liquid crystal display panel provided by the invention is better in display quality.

Description

technical field [0001] The invention relates to the field of plane display, in particular to a liquid crystal display panel. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) is a commonly used electronic device. Due to its low power consumption, small size, and light weight, it is favored by users. The current liquid crystal display is mainly a thin film transistor (Thin Film Transistor, TFT) liquid crystal display (TFT-LCD). The TFT-LCD mainly comprises a TFT array substrate, a color filter (Color Filter, CF) substrate, and a liquid crystal layer disposed between the TFT array substrate and the CF substrate. In order to keep the TFT-LCD with a uniform cell gap, a certain number of spacers (Photo Spacers, PS) are usually arranged inside the TFT-LCD. Specifically, the spacer is disposed between the TFT array substrate and the CF substrate to support the TFT array substrate and the CF substrate, thereby maintaining a uniform cell thickness...
