Abstract: A display panel and a display device are provided. The display panel includes a fingerprint identification area, at least one support unit, and a pixel definition layer. The fingerprint identification area includes a light-transmitting area and a non-light-transmitting area. The support unit is disposed in the light-transmitting area and the non-light-transmitting area. The pixel definition layer includes a plurality of aperture areas each exposing at least one light-emitting unit. Each aperture area has a first neighboring side adjacent to a support unit having a second neighboring side disposed opposite to the first neighboring side. The second neighboring side has an effective length that is parallel to and directly facing the first neighboring side, and the effective length is smaller than a length of the first neighboring side; or, the support unit is disposed adjacent to the first neighboring side, which is a short side of the aperture area.

Abstract: The present disclose provides a display panel and a display device. The display panel includes a display area, a non-display area surrounding the display area, at least one notch, a cathode layer, a peripheral bus, and shift registers. A first non-display area and a second non-display area are oppositely disposed, and a third non-display area and a fourth non-display area are oppositely disposed. A cathode layer includes a cathode connection portion. A peripheral power bus is connected to the cathode connection portion in a cathode contact region. A first cathode contact region and first shift registers are located in a notched non-display area and are overlapped with each other. A second cathode contact region is located in the fourth non-display area. A width of the first cathode contact region in a first direction is less than a width of the second cathode contact region in a second direction.
