Abstract

The invention relates to the technical field of display, and provides a display panel and a display device. The display panel comprises a bending area and a non-bending area, and the display panel further comprises a substrate, a reflection electrode layer, a light emitting layer, a transparent electrode layer, a first phase difference layer and a polaroid. The reflection electrode layer is arranged on the substrate, the light-emitting layer is arranged at one side, deviating from the substrate, of the reflection electrode layer, and the transparent electrode layer is arranged at one side, deviating from the substrate, of the light-emitting layer. The first phase difference layer is arranged at one side, deviating from the substrate, of the transparent electrode layer, is positioned in thebending region and is used for enabling the light with a first preset wavelength and penetrating through the first phase difference layer to generate a phase difference pi, and the polaroid is arranged at the side, deviating from the substrate, of the transparent electrode layer and is located in the non-bending area. The display panel provided by the invention can prevent the display of the bending area from yellowing.

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] OLED display panels have become the main direction of research and development in the display field due to their characteristics such as self-illumination, wide viewing angle, wide color gamut, high contrast, thinness, foldability, bendability, thinness and portability. [0003] The display area of ​​a bendable OLED display panel generally includes a bending area and a non-bending area. In the related art, the bending area of ​​the display panel may appear yellowish. [0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present invention, and therefore may include information that does not constitute prior art known to those of ordinary skill in the art. Contents of the invention [0005]...
