Problems solved by technology
[0002] At present, narrow-frame display panels are gradually becoming the mainstream of display. For OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) rigid display products, encapsulation glue is required for packaging. In this case, it is easy to vapor-deposit the material of the cathode layer on the pad metal of the encapsulant, which affects the adhesiveness of the package and causes the package to fail. At the same time, a green line on the edge will be generated, which will affect the overall black effect of the appearance of the display panel.

Abstract
The invention discloses a display panel and a display device. The display panel is provided with a display area and a non-display area; the non-display area surrounds the display area; the display panel comprises a substrate, a device layer and a packaging part; the device layer is arranged on one side of the substrate and covers the display area, and the device layer comprises a cathode layer; the packaging part is arranged around the device layer in the non-display area, the packaging part comprises a metal cushion layer surrounding the cathode layer, and a gap is formed between the metal cushion layer and the cathode layer; the cathode layer is provided with a first special-shaped edge, the first special-shaped edge is provided with first deformation parts and second deformation parts which are alternately distributed, the first deformation parts protrude and extend towards the direction of the metal cushion layer, and the second deformation parts are sunken and extend towards the direction away from the metal cushion layer; and in the extending direction of the first special-shaped edge, the length of the first deformation parts is smaller than or equal to that of the second deformation parts. The possibility that the cathode layer is evaporated on the metal cushion layer is reduced, the packaging reliability of the packaging part is improved, meanwhile, edge green lines are avoided, and the integrated black effect of the display panel is guaranteed.
Description
Technical field [0001] The present invention belongs to the field of display, and more particularly to a display panel and a display device. Background technique [0002] At present, the display panel of the narrow border is gradually displayed mainstream, and the laptop is packaged for the OLED (OrganicLight-EmittingDiode, Organic Light Emitting Diode), and the encapsulation is applied. Due to the display panel border width and process limit, the cathode layer of the display panel When it is easy to vap into the cushion metal of the encapsulating glue, the adhesion of the package is affected, causing the package failure, and the edge greenery will affect the display panel appearance. Inventive content [0003] The embodiment of the present invention provides a display panel and a display device, which reduces the likelihood of the cathode layer onto the metal pad layer, improves the package reliability of the package portion, while avoiding the edge green line to ensure the int...
