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.
