Abstract

The invention provides a display panel. The display panel comprises a first substrate, a second substrate and a liquid crystal layer; a black matrix is arranged on one side, facing the first substrate, of the second substrate; a spacer layer is arranged on one side, facing the second substrate, of the first substrate; the spacer layer comprises a plurality of first spacers and second spacers; wherein the first spacers and the second spacers are oppositely located below the black matrix, at least the first spacers and the black matrix are arranged in a staggered mode, and the first spacers andthe black matrix are in butt joint to support the first substrate and the second substrate. According to the display panel, the first substrate and the second substrate in the display panel are supported in the mode that the spacers and the black matrix are in butt joint, pressed displacement of the spacers can be effectively reduced, meanwhile, an alignment film is prevented from being scratched,and a dark-state spot light leakage phenomenon is prevented.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a display panel. Background technique [0002] Thin-film transistor liquid crystal display (TFT-LCD) is a device that uses a thin-film transistor to control the tilting state of liquid crystal pixels between two parallel glass plates to produce light-shielding and light-transmitting effects and display images. In order to prevent poor dark state display of TFT-LCD, spacers are needed to support the upper and lower glass plates to maintain the uniformity of liquid crystal thickness. [0003] Usually, the spacers are elastic columnar structures with two different heights. The one with a height slightly larger than the thickness of the liquid crystal cell is the main spacer, and the one with a height smaller than the thickness of the cell is the secondary spacer. [0004] However, under the action of external pressure, traditional spacers are prone to slip, scratchin...
