Abstract: A display panel includes a first display region, a second display region partially surrounding the first display region, and a third display region partially surrounding the first and second display regions. The first display region has a larger light transmittance than the third display region, and the first display region includes an effective light-transmission region and a wiring region located on at least one side of the effective light-transmission region. The display panel includes first and second pixel circuits in the second display region; third pixel circuits in the third display region; first data lines, connected to the first and third pixel circuits; and second data lines, connected to the second and third pixel circuits. Each first data line includes a first sub-data line in the wiring region, a second sub-data line in the second display region, and a third sub-data line in the third display region.

Abstract: A display panel and a display device are provided. The display panel has a display area including first and second display areas. First light-emitting units and first pixel circuits are provided in the first display area, and second light-emitting units and second pixel circuits are provided in the second display area. The second display area includes at least one light-shielding area and at least one light-transmitting area. At least one second pixel circuit of the second pixel circuits is located in the at least one light-shielding area, and at least one second light-emitting unit of the second light-emitting units is located in the at least one light-transmitting area. One of the at least one second light-emitting unit is connected to one of the at least one second pixel circuit through one of anode connection lines.
