Abstract

The application discloses a display panel. The display panel comprises a first substrate, a second substrate and a liquid crystal layer. Spacing columns are arranged between the first substrate and the second substrate; the spacing columns are divided into main spacing columns and sub spacing columns, each main spacing column is divided into a first section of main spacing column and a second section of main spacing column, one side of the first section of main spacing column is arranged on one side of the first substrate, first grooves are formed in the periphery of the lower end surface of the first section of main spacing column, and a convex part is arranged in the middle of each first groove; a first groove in the lower end of the first section of main spacing column surrounds the upper end surface of the second section of main spacing column and cooperates with the second section of main spacing column. The display panel has the beneficial effects that the structure of the spacing columns in the display panel is different from that of common spacing columns, so that when the display panel is subjected to an external force, the convex parts can apply counter-acting forces to the main spacing columns; the thickness of the liquid crystal box is readjusted, Mura is eliminated, and then the display panel can perform normal display.

Description

technical field [0001] The present application relates to the field of communication technologies, in particular to the field of display, and in particular to a display panel. Background technique [0002] In an existing liquid crystal display panel (LCD, Liquid Crystal Display), generally columnar spacers (PS, Photo spacer) are provided to support the upper and lower substrates, so as to ensure uniform thickness of the liquid crystal display panel box. In practical applications, it is often found that the display panel has ring-shaped or horizontal black-and-white band-shaped Mura during the shock test or transportation. After further testing, it is found that the spacer columns corresponding to the Mura area have various degrees of depression, that is, Mura. The height of the spacer column in the area is lower than the normal area, which leads to the abnormal formation of mura in the cell gap. For a long time, the spacer column cannot return to its original state after th...
