Abstract

The embodiment of the invention provides a display panel and a display device. The display panel includes: a substrate; a metal part positioned on the substrate; and a plurality of light-emitting elements located on the side, away from the substrate, of the metal part, wherein each light-emitting element comprises a first electrode, a light-emitting layer and a second electrode which are sequentially stacked in the light emitting direction of the display panel, and the orthographic projection of the metal part on the substrate covers the orthographic projection of the first electrodes and the light-emitting layers on the substrate. According to the embodiment of the invention, the first electrodes have a relatively flat surface, so that the probability of mutual interference between ambient light reflected by the first electrodes is reduced, the dispersion phenomenon of the display panel in a dark state can be improved, and the appearance quality is improved; and meanwhile, the relatively flat first electrodes can also reduce the color difference of pixel light-emitting area colors at different viewing angles, the large-viewing-angle color cast problem of the display panel is improved, and the display effect is improved.

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] Organic Light Emitting Display (OLED, Organic Light Emitting Display) is used as a light-emitting element in an organic light-emitting display device, which has the characteristics of self-luminescence, does not require an additional light source, is conducive to the overall thinning of the display device, and can realize the production of flexible display screens . In addition, organic self-luminous display technology also has the characteristics of fast response speed and wide viewing angle, which has become the focus of current research. [0003] The current organic light-emitting display panel has obvious color dispersion phenomenon under external ambient light, which affects the appearance quality of the product. . Contents of the invention [0004] Embodiments of the present invention provide ...
