A display panel and a display device. The display panel has a first display area and a second display area. The first display area includes a central region and an edge region adjacent to the central region. The first display area has a light transmittance greater than that of the second display area. The display panel includes a plurality of repetitive units, each of which includes at least two pixels, each pixel including a plurality of sub-pixels in at least three colors. Each of the sub-pixels includes a first electrode, a light-emitting structure, and a second electrode stacked in sequence. In the first display area, the first electrodes of adjacent sub-pixels of an identical color in the repetitive unit are electrically connected via an interconnection structure in order to form at least three pixel groups and each of the pixel groups is in a same color.
