Abstract

The invention discloses a display panel, a display device and a preparation method of the display panel. The display panel comprises an array substrate, a pixel definition layer, a light emitting layer and a first electrode, wherein the pixel defining layer is located on the array substrate and comprises an opening area and a pixel defining area surrounding the opening area, the light emitting layer is located in the opening area, and the first electrode is located on the side of the light emitting layer away from the array substrate and comprises a first thinning area corresponding to the opening area. The display panel is advantaged in that adhesiveness between the first electrode and the light emitting layer can be increased, a film stripping phenomenon caused by bending is avoided, andbending performance of the display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a display device and a method for preparing the display panel. Background technique [0002] Organic Light Emitting Diode (OLED) display panels have the advantages of self-illumination, low power consumption, fast response, wide viewing angle, etc., and are widely used in the field of flexible displays. [0003] However, due to the bending stress between the various film layers of the flexible display panel, the film layers are prone to be peeled off when the flexible display panel is bent, resulting in display failure. [0004] Therefore, there is an urgent need to produce a display panel that can effectively improve film peeling. Contents of the invention [0005] The invention provides a display panel, a display device and a preparation method of the display panel. The display panel can alleviate or eliminate the peeling off of the film layer during the be...
