1. A display panel, comprising a non-display area and a display area located inside the non-display area, wherein a gate signal source connected to the non-display area and configured to generate a gate signal is disposed outside one end of the non-display area;
the display area comprises: a substrate base plate, a gate signal layer, a non-metal layer, and a metal layer, wherein the metal layer and the gate signal layer are in a spaced arrangement; and
the gate signal layer comprises more than two gate signal lines in a parallel and spaced arrangement, one ends of the gate signal lines are connected to the gate signal source, other ends of the gate signal lines extend away from the end of the gate signal source, the metal layer comprises more than two scan lines in a parallel and spaced arrangement, one scan line corresponds to one gate signal line, and the scan line is electrically connected to the corresponding gate signal line through a first via hole, wherein
a fracture is provided on each of the gate signal lines, to divide the each gate signal line into a first signal line segment and a second signal line segment in a spaced arrangement, and the first signal line segment is connected to the gate signal source and electrically connected to the corresponding scan line through the first via hole;
the display area further comprises an annular repair circuit located inside the anti-static electrode line and disposed on a face of the non-metal layer that faces away from the gate signal layer, the first signal line segment and the second signal line segment intersect with an orthographic projection of the repair circuit that is on the gate signal layer, and are electrically connected to the repair circuit, and the scan line is electrically connected to the second signal line segment;
when the first signal line segment is abnormal, a second via hole extending through the non-metal layer is formed on a surface of the repair circuit that corresponds to an intersection with each first signal line segment, and the first signal line segment is electrically connected to the repair circuit through the second via hole, so that the gate signal in the first signal line segment is transmitted to the repair circuit;
a third via hole extending through the non-metal layer is formed on a surface of the repair circuit that corresponds to an intersection with each second signal line segment, and the second signal line segment is electrically connected to the repair circuit through the third via hole, so that the gate signal in the repair circuit is transmitted to the second signal line segment; and
the scan line is electrically connected to the second signal line segment through a fourth via hole, so that the gate signal in the second signal line segment is transmitted to the scan line.
