Abstract

A display panel includes a substrate, a pad, an auxiliary electrode layer, a data line layer, a first electrode layer, a light emitting layer, and a second electrode layer. The substrate has a display area and a peripheral area. The pad is disposed on a side of the substrate and located in the peripheral area. The auxiliary electrode layer is disposed on the same side of the substrate as the pad; the data line layer is disposed on a same layer as the auxiliary electrode layer; the first electrode layer is disposed on a side of the auxiliary electrode layer facing away from the substrate; the light emitting layer is disposed on a side of the first electrode layer facing away from the substrate; and the second electrode layer is disposed on a side of the light emitting layer facing away from the substrate and connected to the auxiliary electrode layer.
