Abstract

The embodiment of the invention provides a display panel and a display device, relates to the technical field of display, and aims at weakening a metal visible phenomenon and effectively improving the light extraction efficiency of the panel on the premise of not influencing the service life of a light-emitting element. The display panel comprises a substrate; a light-emitting element which is positioned on the substrate; a pixel definition layer which is positioned on the substrate and is provided with a plurality of first openings, a first reflecting layer which is located at one side, opposite to the substrate, of the pixel defining layer and is provided with a plurality of second openings corresponding to the first openings, wherein the orthographic projection of the first reflecting layer on the substrate covers the orthographic projection of the pixel defining layer on the substrate, and the area of the second openings is smaller than that of the first openings corresponding to the second openings; a shading layer which is located at the side, opposite to the substrate, of the first reflecting layer and is provided with a plurality of third openings corresponding to the second openings, wherein the orthographic projection of the shading layer on the substrate covers the orthographic projection of the first reflecting layer on the substrate.

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 Electroluminescence Display (OLED) display panels have been widely used due to their excellent characteristics such as high brightness, high efficiency, wide viewing angle, and self-luminescence. [0003] As is well known, an OLED display panel is provided with a plurality of light emitting elements. For the top light-emitting element, the anode in the light-emitting element is an opaque reflective electrode. When the external ambient light enters the panel and is transmitted to the anode, it will be reflected back to the human eye by the anode, making the metal visible. In order to solve the above problems, at present, a layer of optical filter is usually arranged on the side of the light-emitting element facing the light-emitting direction, and the optical filter is used to filter the exte...
