Abstract: The present disclosure provides a display panel and a display device including a display area and a non-display area. The display area includes light emitting areas and signal lines, an optical area, and a normal area outside the optical area. The normal area includes a non-transmission area including light emitting areas, and the optical area includes a transmission area and a non-transmission area including light emitting areas. At least one first type signal line extending through the optical area among the signal lines includes a transparent line part in the transmission area of the optical area and a non-transparent line part in the non-transmission area of the optical area. The transparent and non-transparent line parts are in different layers. Through the foregoing configuration, the transmittance of the first optical area with which a first optical electronic device is overlapped can be improved.
