A display panel includes a substrate, a device layer, and an encapsulation layer. The substrate includes a first edge and a second edge intersecting with each other. An included angle between the first edge and the second edge is a first included angle, and the first included angle is a right angle. The encapsulation layer is located on a side of the device layer away from the substrate, and the encapsulation layer covers the device layer along a direction perpendicular to a plane of the substrate. The encapsulation layer includes a first side structure, a second side structure, and an arc-shaped structure located between the first side structure and the second side structure. The first side structure is adjacent to the first edge, the second side structure is adjacent to the second edge, and an angular bisector of the first included angle passes through the arc-shaped structure.
