Problems solved by technology

[0004] When the coating area of ​​the sealant is narrowed, there will be problems of glue opening, liquid crystal leakage and water vapor entering the circuit structure (such as GOA, Gate On Array, array substrate row drive) and corroding the circuit due to insufficient adhesion of the sealant Significantly increased, seriously reducing product yield

Abstract

The invention provides a display substrate, a preparation method thereof, a display panel and a display device and relates to the technical field of display. The adhesion between a frame sealant and the display substrate can be further improved, and the product yield is increased. The display substrate is divided into a display area and a frame sealant setting area located outside the display area; the display substrate comprises a substrate body and a film layer disposed on the substrate body; the part, located in the frame sealant setting area, of the film layer is provided with a penetrating part; the film layer is provided with a bottom surface in contact with the substrate body; the penetrating part includes sidewalls and a lower opening adjacent to the substrate body; the parts, close to the bottom surface, of the sidewalls are inclined toward the lower opening. Preparation of the display substrate, the display panel including the display substrate and the display device including the display substrate is also provided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate and a preparation method thereof, a display panel, and a display device. Background technique [0002] A liquid crystal display panel is mainly composed of an array substrate, a color filter substrate, a liquid crystal layer, and a sealant. Among them, the sealant is coated between the array substrate and the color filter substrate in a ring shape to bond the above two substrates, and the liquid crystal layer is limited in the ring-shaped area of ​​the sealant to prevent the liquid crystal layer from Give way. [0003] With the continuous development of display technology, the existing display products have entered the era of full screen, and the design requires that the frame of the display product be narrower, so that the area for coating the frame sealant between the array substrate and the color filter substrate becomes smaller. few. [0004] W...
