Abstract

The invention discloses a display panel and a display device, and aims to solve the problem that sub-pixels of other colors are slightly bright when R, G and B single-color pictures are displayed on an OLED display panel in the prior art. The display panel is provided with a plurality of pixels. The display panel comprises a substrate, a plurality of first electrode layers, a barrier layer, a common layer and a second electrode layer, wherein the first electrode layers, the barrier layer, the common layer and the second electrode layer are sequentially located on one side of the substrate; thefirst electrode layer comprises a plurality of first electrodes; the barrier layer comprises a plurality of barrier parts located at a gap between every two adjacent first electrodes, and the commonlayer covers the barrier parts and the first electrodes; the barrier part between every two adjacent pixels with different light emitting colors is provided with at least one first concave structure,and the common layer is provided with a second concave structure in the area corresponding to the first concave structure.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) display technology has received widespread attention due to its thinner, lighter, flexible and wide viewing angle. [0003] However, the OLED display panel in the prior art has the problem that sub-pixels of other colors are slightly bright when R, G, and B monochrome images are displayed. Contents of the invention [0004] The present invention provides a display panel and a display device to improve the problem that sub-pixels of other colors are slightly bright when R, G, and B monochrome images are displayed in the OLED display panel of the prior art. [0005] An embodiment of the present invention provides a display panel having a plurality of pixels. The display panel includes: a base substrate, a plurality of first electrode layers sequentially located on one side of the b...
