Abstract

The invention provides a display substrate and a preparation method thereof, a display panel, and a display device, which relate to the field of display technology and can further improve the adhesion between a frame sealant and a display substrate and improve product yield. The display substrate is divided into a display area and a sealant setting area outside the display area; the display substrate includes: a substrate; a thin film layer arranged on the substrate; The part in the frame glue setting area has a through part; wherein, the film layer has a bottom surface in contact with the substrate; the through part includes: a side wall and a lower opening close to the substrate; the side wall The upper portion close to the bottom surface is inclined toward the lower opening. It is used for the preparation of a display substrate, a display panel including the display substrate, and a display device.

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...
