    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.

    Abstract: A display panel and an electronic device are provided. The display panel has an inner cut-off region and a partition region adjacent to inner cut-off region. The display panel includes a substrate, a light-emitting layer, and a hole injection layer. The light-emitting layer is on the substrate. The hole injection layer is between the light-emitting layer and the substrate, and the light-emitting layer is on the hole injection layer and away from the substrate. The hole injection layer includes a first hole injection sub-portion in the partition region and a second hole injection sub-portion in the inner cut-off region and between the light-emitting layer and the substrate. A distance between the second hole injection sub-portion and the substrate is smaller than a distance between the first hole injection sub-portion and the substrate, and the first hole injection sub-portion is separated from the second hole injection sub-portion.
