Abstract

The invention discloses a liquid crystal display panel and a display device. The liquid crystal display panel comprises a substrate and a stopping wall, wherein the substrate comprises a display area used for displaying and a sealing area used for sealing, and the stopping wall is formed on the substrate and located between the sealing area and the display area. A coarse structure is arranged on the lateral side, near the display area, of the stopping wall. In this way, by means of the liquid crystal display panel and the display device, the impact force of alignment liquid to the stopping wall can be reduced through the coarse structure of the lateral side of the stopping wall in the coating process of an alignment film; meanwhile, the adhesive force of the alignment liquid to the stopping wall is increased, and therefore the problem that as the alignment liquid refluxes to the display area, the thickness of the alignment film is uneven is solved. 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...
