Abstract: A display panel and a display device are provided. The display panel includes an active layer, a gate electrode layer, and a metal layer. By forcibly pulling down an electrical potential of a scan signal in a first scan line when a pulse rising edge of the scan signal in the second scanning line arrives, an electrical potential falling time of each scan signal in a display area can be shortened. At the same time, a control line is constructed to at least partially overlaps an electrical potential transmission line in a thickness direction of the display panel, to increase an aperture ratio as much as possible.
