Abstract

The invention provides a display panel and a display device. The display panel comprises an array substrate, a planarization layer, an anode layer, a light-emitting device layer comprising light-emitting device units, pixel definition bodies arranged between adjacent light-emitting device units and retaining walls arranged between adjacent light-emitting device units and used for blocking water and oxygen. The retaining walls are in contact with at least one of the planarization layer and the anode layer. The upper surface of the retaining walls is not lower than the upper surface of the pixeldefinition bodies. According to the display panel, the retaining walls for blocking water and oxygen are additionally arranged between adjacent light-emitting device units, so that the water and oxygen are prevented from diffusing in the horizontal direction in the display panel. The water and oxygen resistance of the display panel is improved.

Description

Technical field [0001] This application relates to the display field, and in particular to a display panel and a display device. Background technique [0002] It is known that organic light-emitting diodes (OLEDs) have received great attention from academia and industry because of their wide application value in the fields of solid-state lighting and flat-panel display lamps. [0003] Organic light-emitting materials are very sensitive to water and oxygen. Therefore, how to effectively isolate the organic light-emitting device from the damage of external water and oxygen to ensure the device has a long service life is also one of the hotspots and difficulties in the current display panel research. At present, the more mature packaging process is generally realized by inorganic / organic multiple alternating thin film structure. Among them, the main function of the inorganic layer is to block water and oxygen. The main function of the organic layer is to release the stress between ...
