Abstract

The invention discloses a display panel and a display device. The display panel includes: an array substrate; a pixel definition layer, located on one side of the array substrate, having a plurality of opening areas and a non-opening area surrounding the opening areas; a light-emitting functional layer, including several organic light-emitting devices, and the organic light-emitting devices are located in the opening areas The encapsulation layer is located on the side of the light-emitting functional layer away from the array substrate, and the encapsulation layer includes a first film layer; wherein, the surface of the first film layer away from the light-emitting functional layer includes a first scattering area, and a plurality of first scattering areas are arranged in the first scattering area A scattering microstructure, wherein the orthographic projection of the first scattering area on the pixel definition layer does not overlap with the opening area. Through the present invention, the light extraction efficiency of the OLED display panel can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] Organic light-emitting diodes (Organic Light-Emitting Diodes, OLEDs) use organic materials as semiconductor materials in light-emitting diodes, and these organic materials will emit light when an electric current passes through them. OLED display technology has the advantages of self-illumination, wide viewing angle, high contrast, low energy consumption, etc., and is widely used in smart products such as mobile phones, digital cameras, and notebook computers. And because of its light weight, thin thickness, and bending resistance, it is the research focus of many scholars at home and abroad. [0003] The light-emitting function layer of the organic light-emitting display panel is an organic light-emitting function layer (organic emitting layer, EML), and the organic light-emitting function lay...
