Claim 12:
13. A display panel, comprising:
a substrate;
a planarization layer at a side of the substrate;
a first electrode layer on a surface of the planarization layer away from the substrate and comprising a plurality of first electrodes; each of the first electrodes comprising a planar center portion and an edge portion surrounding the center portion; the edge portion comprising a planarization portion surrounding the center portion and a slope portion connected between the center portion and the planarization portion, and a thickness of the planarization portion being smaller than that of the center portion;
a light-emitting functional layer covering at least part of the center portion; and
a second electrode covering the light-emitting functional layer and comprising a recessed portion and a plurality of flat portions separated by the recessed portion;
wherein orthographic projections of the flat portions on the planarization layer within the first electrodes are in one-to-one correspondence;
wherein the recessed portions are recessed toward a side of the flat portions close to the substrate; and
wherein an orthographic projection of the recessed portion on the planarization layer is at least partially outside the center portion.
