DISPLAY PANEL AND DISPLAY DEVICE

A display panel and a display device. The display panel includes a transition region and a light-transmitting region, and a light transmittance of the light-transmitting region is greater than a light transmittance of the transition region. The display panel includes a driving backplane including a first driving circuit disposed in the transition region, a planarization layer disposed on the driving backplane of the transition region and the light-transmitting region, a first electrode layer disposed at a side of the planarization layer of the transition region and the light-transmitting region, and a plurality of first light-emitting units disposed in the light-transmitting region. The first electrode layer is electrically connected with the first output terminal by extending through the planarization layer, and is configured to provide electrical signals for the plurality of first light-emitting units.
