Abstract: A display panel includes a drive backplane, a first electrode layer, a light-emitting function layer, and a second electrode. The first electrode layer is provided on a surface of the drive backplane and includes a plurality of first electrodes. The first electrode includes a flat middle part and an edge part surrounding the middle part. The edge part includes a horizontal part surrounding the middle part and a climbing part connecting the middle part and the horizontal part. The light-emitting function layer covers the middle part. The second electrode covers the light-emitting function layer and includes a separating part and a plurality of flat parts separated by the separating part. Orthographic projections are located within the first electrodes. The separating part includes a protruding area and first recessed areas connecting the protruding area and the flat parts. Orthographic projections of the first recessed areas are outside the middle parts.
