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 a plurality of 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.
