A double-shielded electroluminescent panel includes an electroluminescent device, an upper electrical shield and a lower electrical shield. The upper electrical shield is a transparent conductive material, and is overlaid on the illuminating surface of the electroluminescent device. The lower electrical shield is an electrical conductive material, and is mounted on the non-illuminating surface of the electroluminescent device. The upper electrical shield and lower electrical shield are together connected to the ground line of a power source. Therefore, the occurrence of electromagnetic interference and an electric shock is avoided.
