Display panel and display device

The invention provides a display panel and a display device. The display panel comprises a display area and a light-transmitting area. The display panel further comprises a plurality of scanning signal lines, a first gate drive circuit and a second gate drive circuit. The scanning signal lines are located in the display area, and at least one scanning signal line is disconnected into a first sub-signal line and a second sub-signal line. The length of the first sub-signal line is smaller than that of the second sub-signal line, and a connecting line of at least one first sub-signal line and the corresponding second sub-signal line passes through the light-transmitting area. The first gate drive circuit comprises a first output module connected with the first sub-signal line. The second gate drive circuit comprises a second output module connected with the second sub-signal line, and the width of the current channel of the first output module is smaller than that of the current channel of the second output modu
