Abstract: The present application discloses a display panel and an electronic device. The display panel includes a display area and a redundant pixel area located on at least one side of the display area. The display panel includes a substrate, a power supply wire, a light-emitting function layer, and a cathode disposed in sequence. At least a part of the power supply wire is located in the redundant pixel area; the light-emitting function layer covers the display area and the redundant pixel area; and the cathode is electrically connected to the power supply wire.

Abstract: A display panel, a manufacturing method thereof, and a display device are provided. In the display panel, a first undercut structure and a second undercut structure are formed along a vertical direction of an overlappingly connecting hole of the first electrode layer and the auxiliary electrode layer. Therefore, an overlappingly connecting area between the first electrode layer and the auxiliary electrode layer can be enlarged. As such, the first electrode layer can be ensured to have high transparency and good conductivity, thereby solving an issue of IP drop of the first electrode. In addition, by using this undercut structure as well as using a metal line layer to overlappingly connect the first electrode layer with the auxiliary electrode layer, the overlappingly connecting area between the first electrode layer and the auxiliary electrode layer can be enlarged without reducing an aperture ratio of the display panel.
