Abstract

The invention provides a display panel, a preparation method thereof and a display device, and belongs to the technical field of display panels. The display panel comprises a substrate, a first electrode contact part, a light emission layer and a first electrode; the first electrode contact part is arranged on the substrate and surrounding a display area, and isolated from the display area by an isolation area; the light emission layer covers the display area and at least part of the isolation area, and at least part of the light emission layer extends to the inner edge of the first electrodecontact part or the surface, far from the substrate, of the first electrode contact part; and the first electrode is arranged on part, not covered by the light emission layer, of the light emission layer and the first electrode contact part. In the display panel, connection between the first electrode and the first electrode contact part is highly stable, and the stability and yield rate of the display panel are high.

Description

technical field [0001] The present disclosure relates to the technical field of display panels, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the development of organic light-emitting technology, the application of OLED is more and more extensive. [0003] Such as figure 1 and figure 2 As shown, the existing OLED display panel mainly includes a base substrate 1, a second electrode 6 disposed on the base substrate 1, and a first electrode contact part 2, which is disposed on the second electrode 6 and contacts the first electrode. The first electrode 4 connected to the part 2, and the light emitting layer 3 provided between the first electrode 4 and the second electrode 6. The display area 5 is separated from the first electrode contact portion 2 , and the position between them is called an isolation area 7 . Wherein, the first electrode 4 is easily broken when connected to the first electrode c...
