The present application belongs to the technical field of display. Disclosed are a display panel, a method for manufacturing a display panel, and a display apparatus. The display panel comprises a substrate, a plurality of light-emitting units located on the substrate, and a plurality of protruding structures located on the side of the plurality of light-emitting units away from the substrate, wherein each protruding structure comprises a central area and an edge area located outside the central area. In the present application, by making the roughness of a central area less than that of an edge area, with this structure, light emitted by a plurality of light-emitting units can be converged by the protruding structure. Due to higher roughness of the edge area of the protruding structure, the capability of the edge area to converge light can be reduced, and a viewing angle of a display panel can be increased while ensuring a certain brightness in a direct viewing angle direction, thus solving the problem in the related art of a viewing angle of a display panel being relatively small, and achieving the effect of improving a viewing angle of a display panel.

A recessed region (2105) is formed between two adjacent pixel electrodes (221) on the surface of the pixel definition portion away from a drive backplane (1). A bottom surface of the recessed region (2105) comprises a first smooth curved section protruding in a direction away from the drive backplane (1). The bottom surface of the recessed region (2105) is provided with a partition recess (2102). A common electrode (222) forms a protruding portion (2221) in an orthographic projection region of the partition recess (2102). The protruding first smooth curved section can enable the contour of the protruding portion (2221) to become curved, and increases the distance between the protruding portion (2221) and the pixel electrodes (221), such that the probability that the protruding portion (2221) punctures and contacts the pixel electrodes (221) is greatly reduced, thereby reducing the risk of short circuits between the common electrode and the pixel electrodes while ensuring the partitioning of a light-emitting layer group.
