A display panel and a display device are provided. The display panel has a main display area and a light-transmitting display area, including: a first electrode layer including multiple first electrodes arranged at intervals; a pixel definition layer is provided with multiple first via holes; a light-emitting layer group is at least partially arranged within the first via holes, and the light-emitting layer group located within the first via holes forms light-emitting parts; in the light-transmitting display area, a second electrode layer includes multiple second electrodes and connection wires connected with each other; the multiple second electrodes are arranged at intervals, the second electrodes are located on a side of the light-emitting parts away from a base substrate, and orthographic projections of the second electrodes on the base substrate cover orthographic projections of the first electrodes on the base substrate.
