摘要： Disclosed is an electroluminescent display panel and a display device, and relates to the field of display technologies. The display region comprises a photosensitive device arranging region, a camera or fingerprint recognition device is arranged in the photosensitive device arranging region, rather than in the frame, and thus a relatively larger area occupying in the frame is avoided, to allow the frame be made narrower, and the screen-to-body ratio be increased. Also for the photosensitive device arranging region, the first signal lines and the second signal lines are arranged more intensively by arranging overlap areas in the orthographic projection of one first pixel on the base substrate, to allow the display panel have more concentrated space as the light-transmission region, so that the light transmittance of the photosensitive device arranging region can be increased to provide more lights to the camera or fingerprint recognition device.
