Abstract

The invention provides a display panel and a manufacturing method thereof. The display panel comprises a semi-finished product area and a cutting area, wherein a cutting boundary is formed between the semi-finished product area and the cutting area; the first substrate and the second substrate are oppositely arranged; the first supporting piece is located in the semi-finished product area and close to the cutting boundary, the second supporting piece is located in the cutting area and close to the cutting boundary, and the height of the second supporting piece is smaller than a distance between the first substrate and the second substrate; during splitting, the first supporting piece supports the display panel in the semi-finished product area, so a stress difference is formed between the display panel in the cutting area and the display panel in the semi-finished product area; a height difference is formed between the second supporting piece and the distance between the first substrate and the second substrate, so curvature of the first substrate and the curvature of the second substrate in the cutting area are different; under the action of the stress difference and the curvature difference, a purpose of reducing the corner cutting and cracking difficulty is achieved, the smoothness degree of the section of the display panel is ensured, and production of small-size corner cutting products is achieved.

Description

technical field [0001] The present application relates to the field of display panels, in particular to a display panel and a manufacturing method thereof. Background technique [0002] Liquid crystal display (LCD, Liquid Crystal Display) products need to cut corners, dig holes, etc. for the liquid crystal panel of the LCD in order to realize the functions of product special shape, mechanical strength reinforcement, and overall machine avoidance. [0003] In view of the continuous improvement of the screen-to-body ratio of display products, the size of some cut corners has been continuously reduced. According to the existing laser / cutting process, when dealing with small-sized cut corners, it is easy to cause cut corner lobes because the cut corner size is too small. Contents of the invention [0004] The present application provides a display panel and its manufacturing method to improve the existing laser / cutting process. When dealing with small-sized cut corners, it is...
