WIPO Patent Application WO/2022/082430
Kind Code:
A1
Abstract:
Provided are a display panel and a display device. The display panel comprises: a base substrate; a sub-pixel located on the base substrate, and comprising a pixel circuit and a light-emitting element connected to the pixel circuit, the light-emitting element comprising a first electrode; a first insulating layer located on the side of the pixel circuit distant from the base substrate, the first electrode being connected to the pixel circuit by means of a first via hole passing through the first insulating layer; and a pixel defining layer located on the side of the first electrode distant from the base substrate, and comprising an opening. The first electrode comprises a body portion and a connecting portion, the body portion is connected to the pixel circuit by means of the connecting portion, the orthographic projection of the body portion on the base substrate at least partially overlaps the orthographic projection of the opening on the base substrate, the orthographic projection of the connecting portion on the base substrate at least partially overlaps the orthographic projection of the first via hole on the base substrate, and the size of the connecting portion at the first via hole in a first direction is 1/5 to 4/5 of the size of the body portion in the first direction.
