Abstract: The present application discloses a display panel and a display device. The display panel includes an active layer, a gate layer, and a metal layer, which is able to quickly pull down a falling edge of a scan signal in a first scan line when a rising edge of a scan signal in a second scan line arrives. By constructing a low-potential wiring, a control wiring, and a pull-down transistor between the first data line and the second data line, a layout with less space can be completed and an aperture ratio can be increased as much as possible.

Abstract: A display panel includes a first data line, a second data line, a third data line, a first sub-pixel, a second sub-pixel, a third sub-pixel, and a first transistor. The first sub-pixel is located between the first data line and the second data line, and includes a first pixel electrode. The second sub-pixel is located between the second data line and the third data line, and includes a second pixel electrode. The third sub-pixel is located between the first data line and the second data line, and includes a third pixel electrode. The first transistor is electrically connected to one of the first pixel electrode, the second pixel electrode, and the third pixel electrode. The first transistor includes a first semiconductor. At least a part of the first semiconductor overlaps with the first pixel electrode or the second pixel electrode.

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.
