ABSTRACT:
A hermetic container which can improve its stress resistance and its buckling strength and prevent deformation due to the atmospheric pressure. The space between the anode substrate and the cathode substrate in the hermetic container can be stably maintained. Anode conductors and fluorescent substance layers are formed on the inner surface of the anode substrate. Electron sources are formed on the inner surface of the cathode substrate so as to confront the corresponding display portions on the anode substrate. In order to complete a container, the anode substrate is spaced from the cathode substrate a predetermined distance apart and the fringe portions of the substrates are sealed. A supporting member is disposed in the container. The supporting member 15 consists of a plate in which plural through holes are formed at predetermined intervals and reinforcing supports which are respectively inserted into the through holes of the plate and of which the middle portions are bonded at the inlets of the through holes. Each reinforcing support has one end in contact with an inner surface of the anode substrate and the other end in contact with an inner surface of the cathode substrate. Each reinforcing support maintains the gap between the anode substrate and the cathode substrate at a fixed distance.
