Abstract
A display panel including a pixel driving circuit is provided. The pixel driving circuit includes a first pixel driving circuit layer, a second pixel driving circuit layer, and a capacitor. The capacitor is electrically connected with a transistor of the first pixel driving circuit layer. The capacitor includes a first electrode plate. The second pixel driving circuit layer is arranged on the first electrode plate. At least one transistor of the second pixel driving circuit layer at least partially overlaps with the first electrode plate, so that the space occupied by the pixel driving circuit can be saved.
