    Abstract: A hermetic container which does not require a getter room and can reliably absorb gases released in a container. In a field emission display, the hermetic container contains a front substrate and an opposite substrate confronting each other and a spacer disposed between the outer fringes of the front substrate and the outer fringes of the opposite substrate. Stripe anodes are formed on the inner surface of the front substrate. Each anode is formed of a transparent anode conductor and a fluorescent substance layer. Field emission elements are formed on the inner surface of the opposite substrate and respectively have a cathode conductor, an insulating layer, a gate, and an emitter disposed in an opening. Each of supports has one end which is disposed between stripe anodes and is in contact with the front substrate and the other end which is disposed between stripe gates and is in contact with the insulating layer.
