Abstract

The invention discloses a display panel and a display device.The display panel comprises a substrate and a plurality of light-emitting devices, the light-emitting devices are located on one side of the substrate, and each light-emitting device comprises an anode and an organic light-emitting layer which are arranged in a stacked mode; the organic functional layer is positioned on one side, facing the anode, of the organic light-emitting layer; the organic functional layer comprises a first organic functional part and a second organic functional part, and the first organic functional part and the organic light-emitting layer are at least partially overlapped in the direction perpendicular to the plane where the substrate is located; in the first direction, the first organic function part is in contact with the second organic function part, the material of the first organic function part is different from that of the second organic function part, and the first direction intersects with the light emitting direction of the display panel. The material of the first organic function part is different from the material of the second organic function part, so that drift of carriers in the first direction is reduced, and the display effect is 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] With the development of OLED display technology, more and more attention has been paid to the full-color display of OLED. At present, the structure and design of OLED devices are mostly formed by combining and superimposing multiple layers of materials. By controlling the voltage and current of the pixel circuit, the brightness and darkness of the light-emitting layer of the OLED device structure can be controlled. However, the current OLED device structure cannot avoid lateral leakage between sub-pixels, which will lead to stealing of sub-pixels, resulting in color crosstalk and abnormal display. [0003] Then, how to avoid the problem of sub-pixel stealing and improve the display effect of the display panel is a technical problem to be solved urgently by those skilled in the art.
