    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 light-emitting diode display panel, a manufacturing method thereof, and an organic light-emitting diode display device are provided. The light-emitting diode display panel includes: a base substrate including a display region and a peripheral region surrounding the display region; a plurality of sub-pixels located in the display region and located at a side of the base substrate; a color-resistance layer located at a side of a second electrode in the sub-pixel away from the base substrate; and a light-blocking structure located in the peripheral region and being an annular structure surrounding the plurality of sub-pixels. The light-blocking structure includes a first light-blocking structure and a second light-blocking structure. The first light-blocking structure includes at least one interval extending in a direction from the display region pointing to the peripheral region. The second light-blocking structure at least fully fills the interval.
