Abstract: A display panel comprises a hole, a transition region, and an image display region. A display layer of the display panel is located on a side of a substrate and includes a first cathode portion. The display panel further includes an isolation column located in the transition region, and a first film layer is in contact with the isolation column. The isolation column includes an insulation isolation portion. A part of a side wall of the insulation isolation portion is recessed toward an inside of the insulation isolation portion to form a groove. A first surface of a side of the insulation isolation portion is away from the substrate. The first cathode portion extending on the first film layer is separated at the groove from the first cathode portion extending on the first surface.
