The display panel includes: a via hole penetrating through the display panel; a cutting residual region, and a packaging layer located on one side of the base substrate; and at least one circle relief structure located between the packaging layer and the base substrate of the cutting residual region. The at least one circle relief structure is distributed around the via hole. The smallest distance between a first relief structure and the outer edge of the via hole ranges from 0 to 30 micrometers. At least one relief structure is provided with a surface facing away from the base substrate, and a side face connected to the surface, where at least one of the surface and the side face is of a relief shape. The first relief structure is a relief structure with a smallest distance from a center of the via hole.
