In order to ensure hermeticity of a hermetic container and to suppress occurrence of electrical leakage, a display device is provided with a faceplate including an anode to be supplied with an externally-supplied electric potential, a rear plate arranged facing the faceplate at a predetermined spacing therefrom, a metal pin for supplying the electric potential to the anode from outside of the rear plate through a penetration hole in the rear plate, wherein the penetration hole includes the metal pin by insertion. The metal pin includes an axis portion disposed in the penetration hole and a flange portion which is integral with this axis portion and which is located adjacent an opening end of the penetration hole. The flange portion is joined to the rear plate for hermetically sealing the penetration hole.
