Problems solved by technology

[0004] However, due to the self-luminous characteristics of the organic light-emitting display panel, the background light from the outside will directly enter the panel and be reflected by the metal in the panel, so that the display contrast will decrease. A polarizer is attached to the light-emitting side, so as to eliminate the background light and improve the display contrast

Abstract

The invention relates to a display panel and a display device. The display panel comprises a substrate, an array layer, a light-emitting functional layer, a packaging layer, a polarization functionallayer and a first buffer layer, wherein the substrate, the array layer, the light-emitting functional layer and the packaging layer are arranged in sequence; the polarization functional layer is positioned on the side, which is away from the light-emitting functional layer, of the packaging layer; the first buffer layer is positioned on at least one side surface of the polarization functional layer and contacted with the polarization functional layer; the edge of polarization functional layer is sunken towards the center of the polarization functional layer in the direction parallel to the display panel to form at least one notch; the edge of the first buffer layer protrudes in the direction away from the center of the first buffer layer in the direction parallel to the display panel to form at least one protruding portion; the display panel is a bendable display panel; the protruding portion is overlapped with the notch; and the bending axis of the display panel passes through the protruding an overlapping area of the protruding portion and the notch. The invention further provides a display device including the display panel. According to the invention, the bending reliability ofthe display panel can be improved, and the generation of cracks of a film layer in the display panel is avoided when the display panel is bent.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device including the display panel. Background technique [0002] With the continuous development of display technology, the display panel manufacturing technology is also becoming mature. Considering the light-emitting effect of existing display panels, it is often necessary to integrate polarizers into the display panel. [0003] For example, Organic Light Emitting Diode (OLED) display panels are widely used in the display field due to their advantages such as self-illumination, low power consumption, fast response, and wide viewing angle. [0004] However, due to the self-luminous characteristics of the organic light-emitting display panel, the background light from the outside will directly enter the panel and be reflected by the metal in the panel, so that the display contrast will decrease. A polarizer is attached to the light-emitting side, so as...
