Problems solved by technology

During long-term use, PS will generate friction with the PI material, which will easily scratch the PI material on the substrate, causing the PI material to peel off and generate debris, which will be transferred to the display area after being tapped, resulting in broken bright spots
As a result, the brightness of the dark state of the liquid crystal is relatively high, which affects the contrast of the liquid crystal display and is not conducive to improving the quality of the product.

Abstract

The embodiment of the present application discloses a display panel, the display panel includes a first substrate and a second substrate oppositely arranged, and a main spacer formed on the first substrate and abutting against the second substrate, on the first substrate and An accommodating cavity is also formed between the second substrates, the accommodating cavity has an opening, and the abutting part of the main spacer and the second substrate is adjacent to the opening of the accommodating cavity. In the embodiment of the present application, the debris generated by scratching the PI material is collected and stored through the accommodation cavity formed between the first substrate and the second substrate, reducing the probability of debris entering the display area and forming broken bright spots, preventing the reduction of the dark state of the liquid crystal Brightness, improve the contrast of the LCD panel.

Description

technical field [0001] The present application relates to the technical field of liquid crystal display, in particular to a display panel. Background technique [0002] In the display panel design of liquid crystal display, it is mainly divided into array substrate (also called array substrate, lower panel) and color filter substrate (also called CF substrate, upper panel). Array process and CF process are carried out in the early stage, and then Fit and assemble together by means of frame glue or the like. In the display area of ​​the display panel, the supporting material between the upper plate and the lower plate is a spacer (Photo Spacer, also known as PS, film column, spacer, generally a columnar body), which is used in the process of panel transportation or display. Play a supporting role. If the spacer is deposited on the array substrate, the spacer will be in close contact with the PI material (an insulating material) of the upper plate when supporting the upper p...
