Problems solved by technology

In the process of PI film coating, it is easy for the PI film to cross the sealing area, resulting in puncture in the later seal, causing the sealant to fall off, and then causing the problem of seal failure.
In order to solve the above problems, an existing solution is to coat the PI film away from the sealing area, but this is prone to the problem that the PI film cannot completely cover the display area, and then the liquid crystal display panel cannot display normally.

Abstract

The invention discloses a liquid crystal display panel and a display device. The liquid crystal display panel comprises a substrate, an OC layer and a stopping wall, wherein the OC layer is formed on the substrate and comprises a display area used for displaying and a sealing area used for sealing, and the stopping wall is formed on the OC layer and located between the display area and the sealing area. In this way, by means of the liquid crystal display panel and the display device, an alignment film and the sealing area can be isolated by the stopping wall in the coating process of the alignment film, and therefore the problems that as the alignment film exceeds the sealing area, puncturing appears during later-period sealing, sealant falls accordingly, and then sealing fails are solved while it is guaranteed that the display area is completely covered with the alignment film. In addition, the coating accuracy and the coating efficiency of the alignment film can be improved by arranging the stopping wall, and then the product yield of the liquid crystal display panel is increased.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display panel and a display device. Background technique [0002] Alignment film (Polyimide, PI) coating is an important process step in the production process of liquid crystal display panels, and is also an important link in the display of liquid crystal display panels. During the coating process of the PI film, it is easy for the PI film to cross the sealing area, resulting in puncture in the later stage of the seal, causing the sealant to fall off, and then the problem of seal failure. In order to solve the above problems, an existing solution is to coat the PI film away from the sealing area, but this is prone to the problem that the PI film cannot completely cover the display area, and then the liquid crystal display panel cannot display normally. Contents of the invention [0003] The technical problem mainly solved by the present invention is to p...
