Abstract

The embodiment of the invention provides an organic light-emitting display panel and a display device. The organic light-emitting display panel comprises a display area and a non-display area surrounding the display area. The display area comprises a substrate, an organic light-emitting layer located on one side of the substrate and comprising a plurality of light-emitting units, a pixel definition layer comprising a plurality of first openings surrounding the light-emitting units, and a micro-lens layer located on one side, away from the substrate, of the pixel definition layer and comprisinga plurality of micro-lenses, wherein the micro lenses are arranged between the adjacent light-emitting units, and the orthographic projections of the micro lenses on the substrate cover the orthographic projection parts of the adjacent light-emitting units on the substrate. According to the invention, the micro lenses are arranged above the areas between the light-emitting units, and the parts ofthe micro lenses are overlapped with the edge parts of the light-emitting units, so large-angle light can be changed into small-angle light, the light passing through the edges of the light-emittingunits is limited near the areas where the light-emitting units are located, and the light-emitting efficiency of the light-emitting units is further improved.

Description

【Technical field】 [0001] The present application relates to the field of display technology, in particular to an organic light emitting display panel and a display device. 【Background technique】 [0002] Compared with liquid crystal displays, organic light-emitting displays have many advantages, such as thinner and thinner, higher brightness, lower power consumption, faster response, higher definition, better flexibility, and higher luminous efficiency, and have gradually become the mainstream display technology. The light-emitting principle of the organic light-emitting display is that the holes generated by the anode and the electrons generated by the cathode in the organic light-emitting device move under the action of an electric field, inject them into the hole transport layer and the electron transport layer respectively, and migrate to the organic light-emitting material. When the two meet in the light-emitting material layer, energy excitons are generated, thereby ex...
