Display panel and display apparatus

A display panel, comprising:

• a display area, used for image displaying, and surrounding at least one through hole;
• and
• an isolation area, located between the through hole and the display area surrounding the through hole, wherein
• the isolation area comprises:
• at least two annular blocking dams, wherein the annular blocking dams surround the through hole, and the annular blocking dams are nested;
• and a first metal layer, an insulating layer, and a second metal layer are arranged in a gap between the adjacent annular blocking dams, and the insulating layer is located between the first metal layer and the second metal layer;
• and
• a through hole crack detection line, wound around an edge of the through hole, and configured to perform crack detection on the edge of the through hole, wherein the through hole crack detection line comprises a first detection line and a second detection line, the first detection line is arranged on a layer same as the first metal layer and is electrically connected to the first metal layer, the second detection line is arranged on a layer same as the second metal layer and is electrically connected to the second metal layer, and the first detection line and the second detection line are electrically connected, through a via hole of the insulating layer, to each other at a set position.
