Abstract

The disclosure provides a display panel, a preparation method thereof, and a display device, which belong to the technical field of display panels. The display panel includes a base substrate, a first electrode contact portion, a light-emitting layer, and a first electrode; the first electrode contact portion is arranged on the base substrate and surrounds the display area, and is separated from the display area by an isolation area isolation; the light emitting layer covers the display area and at least part of the isolation area, and at least partially extends to the inner edge of the first electrode contact part or the surface of the first electrode contact part away from the base substrate; A first electrode is provided on the light emitting layer and a portion of the first electrode contact not covered by the light emitting layer. The stability of the connection between the first electrode of the display panel and the first electrode contact portion is high, and the stability and yield of the display panel are high.

Description

technical field [0001] The present disclosure relates to the technical field of display panels, and in particular, to a display panel, a method for manufacturing the same, and a display device. Background technique [0002] With the development of organic light-emitting technology, the application of OLED is becoming more and more extensive. [0003] like figure 1 and figure 2 As shown, the existing OLED display panel mainly includes a base substrate 1, a second electrode 6 provided on the base substrate 1, and a first electrode contact portion 2, which is provided on the second electrode 6 and is in contact with 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 and the first electrode contact portion 2 are spaced apart, and the position between the two is called an isolation area 7 . Wherein, the first electrode 4 is easily broken when...
