Abstract

A display panel includes: a base substrate, a pixel defining layer, light-emitting portions, an electrode layer, a metal repelling portion, and an auxiliary electrode layer. The pixel defining layer includes opening regions and dams. The light-emitting portions are in the opening regions. The electrode layer is on the side of the light-emitting portions facing away from the base substrate. The metal repelling portion is on the side of the electrode layer facing away from the base substrate and in the opening regions. The auxiliary electrode layer is on the side of the pixel defining layer facing away from the base substrate, and includes auxiliary electrode portions located in the region where the dams are located. The auxiliary electrode portions are in contact with third portions of the electrode layer, and the material of the metal repelling portion and the material of the auxiliary electrode layer repel each other.
