Abstract: The present disclosure provides a display panel including a first area including a plurality of first pixels, and a second area including a pixel area including a plurality of second pixels and a plurality of light-transmitting areas disposed between the plurality of second pixels. Each of the plurality of first pixels and the plurality of second pixels include a light emitting element, such as a light emitting diode, and the light emitting element includes an anode layer and a plurality of cathode layers. The plurality of cathode layers disposed in the second area can be disposed in areas except for the light-transmitting areas. Thus, light transmittance in the light-transmitting areas of the display device can be improved, and the reliability of the display device can be enhanced effectively.

Abstract: Disclosed is an electroluminescence display device having a through-hole in a display area thereof. The electroluminescence display device includes a substrate, a display area, a non-display area, a through-hole, an inner dam, and a concave-convex pattern. In the display area, a plurality of pixels, each of which includes a light emitting element that displays an image and a driving element that drives the light emitting element, are disposed on the substrate. The non-display area surrounds the display area on the substrate. The through-hole is disposed in the display area and does not include the substrate, the light emitting elements, and the driving elements. The inner dam surrounds the through-hole. The concave-convex pattern surrounds the through-hole between the through-hole and the inner dam.
