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 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.

Abstract: The present application provides a liquid crystal display panel, a liquid crystal display device, and an electronic device. By removing portions of a first polarizer and a second polarizer of the liquid crystal display panel that corresponds to a light-transmitting area, light can be transmitted in the light-transmitting area of the liquid crystal display panel. In addition, by setting a first liquid crystal layer in the light-transmitting area of the liquid crystal display panel to allow a portion of the liquid crystal display panel corresponding to the light-transmitting area in a display state.
