Problems solved by technology

[0004] In the related technology, MCL glue is applied to the bending area to reduce the stress of the metal wiring when it is bent. However, the MCL glue has a relatively high viscosity, and it is easy to cling to the surface of the protective film of the polarizer or panel through the siphon effect. In D- When the protective film is torn off in the lami process, the MCL adhesive peeling is caused, so that cracks (panel cracks) easily occur on the edge of the adhesive during the subsequent pad bending, resulting in bright and dark lines, no visible, abnormal display, etc.

Abstract

The invention discloses a display panel and a display device. The display panel comprises a display area and a non-display area, the non-display area comprises a bending area, the display panel comprises a back film, an insulating layer, a signal wiring layer, a polaroid and protective glue, the insulating layer is arranged on one side of the back film, a concave part of the insulating layer is located in the bending area. A blocking structure is formed on the surface of the side, back to the back film, of the signal wiring layer, the polaroid is arranged on the surface of the side, back to the back film, of the signal wiring layer and located on the side, close to the display area, of the concave part, in the second direction, the blocking structure is located between the polaroid and the concave part, and the protection glue is arranged on the surface of the side, back to the back film, of the signal wiring layer.The positive projection of the back film is arranged opposite to the concave part. The blocking structure is used for blocking the protective glue from flowing towards the polaroid, so that the protection glue is connected to the outer side wall, close to the bending area, of the polaroid. The display panel provided by the invention has good bending yield and stability.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the development of display technology, OLED flexible screens are more and more popular with consumers due to their high contrast, flexibility and foldability. The application in various fields is immeasurable. [0003] The lower border of the OLED screen is used as the signal line to lead out IC&FPC bonding process, so that its width is much larger than the other three sides. Therefore, in the process of manufacturing the OLED screen module, pad bending process is required for the lower border. [0004] In the related technology, MCL glue is applied to the bending area to reduce the stress of the metal wiring when it is bent. However, the MCL glue has a relatively high viscosity, and it is easy to cling to the surface of the protective film of the polarizer or panel through the siphon effect. In D-...
