Abstract:
A display panel includes a substrate, a planarization layer disposed at a side of the substrate being provided with partitioning slots to form driving areas in an array; a first electrode layer on the planarization layer having first electrodes; wherein orthographic projections of the first electrodes on the planarization layer are within the driving areas; each of the first electrodes includes a planar center portion and an edge portion, the edge portion includes a planarization portion surrounding the center portion and a slope portion connected between the center portion and the planarization portion; a pixel definition layer on the planarization layer that exposes part of the center portion; a light-emitting functional layer covering the pixel definition layer, the center portion being exposed by the pixel definition layer and the planarization layer and a second electrode covering the light-emitting functional layer.
