Abstract
A display panel includes a display area surrounding a through hole and an isolation area between the through hole and the display area. The isolation area includes at least two annular blocking dams surrounding the through hole. A first metal layer, an insulating layer and a second metal layer are arranged in a gap between the adjacent annular blocking dams. The isolation area further includes a through hole crack detection line wound around the edge of the through hole. The through hole crack detection line includes a first detection line and a second detection line. The first detection line on the same layer as the first metal layer and the second detection line on the same layer as the second metal layer are electrically connected through a via hole of the insulating layer.
