Abstract

The invention discloses a display panel and a display device, and belongs to the technical field of display. The display panel comprises a substrate, an array layer, a pixel definition layer, a light-emitting device layer and an optical structure layer, wherein the optical structure layer comprises a plurality of micro lens units, the orthographic projection of at least part of the micro lens units to the light-emitting surface of the display panel and the orthographic projection of openings to the light-emitting surface of the display panel are mutually overlapped, and the micro lens units are used for converging light entering the micro lens units to the side away from the substrate; the optical structure layer comprises a first optical structure layer and a second optical structure layer, the refractive index of the first optical structure layer is less than that of the second optical structure layer, and the second optical structure layer is made of optical cement. The display device comprises the display panel. According to the invention, the light emitting efficiency of the display panel can be improved, and the second optical structure layer can be multiplexed as a film layer for manufacturing the micro lens unit, so that the thinning of the panel is facilitated, and the material use cost is reduced.

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] With the development of display technology, consumers have higher and higher requirements for audio-visual products. For display manufacturers, the production of high-resolution and high-quality displays is the development direction, while Organic Light Emitting Diode (OLED) Due to its characteristics such as self-illumination, high brightness, wide viewing angle, fast response, and RGB full-color components can be made, it has been widely used in displays. At present, the application of OLED display panels has entered the practical stage, and it will be widely used in Mobile products, notebook computers, monitors, wall-mounted TVs and other thin and light displays, and the development of full color will improve the competitiveness of OLED products. [0003] However, in the prior art, the lumin...
