1. A display panel, comprising a display area and a non-display area connected to the display area, wherein the display panel comprises:
a plurality of scan lines disposed in the display area and extended to the non-display area, wherein the plurality of scan lines are arranged along a first direction;
a GOA circuit disposed in the non-display area, wherein the GOA circuit comprises multi-stage cascaded GOA units;
a plurality of signal transmission lines disposed in the non-display area, wherein each of the GOA units is electrically connected to at least one of the plurality of scan lines through corresponding one of the plurality of signal transmission lines;
at least one repair line disposed between the GOA circuit and the display area and extended along the first direction, wherein the at least one repair line crosses the plurality of scan lines or the plurality of signal transmission lines and is disposed in different layers; and
wherein the at least one repair line is configured to electrically connect one scan line of the plurality of scan lines that transmits a first scan signal abnormally to another scan line of the plurality of scan lines that transmits a second scan signal normally, such that the scan line that transmits the first scan signal abnormally and the scan line that transmits the second scan signal normally transmit the second scan signal simultaneously.
