ABSTRACT:
A display apparatus is disclosed with a vacuum seal member which has a shell structure. The display apparatus includes an anode substrate, a planar cathode substrate forming an electron emitting chamber vacuously sealed between the cathode substrate and the anode substrate, electron sources formed on the cathode substrate, phosphors formed on the anode substrate, and a vacuum seal member forming a pressure balancing chamber on the back of the electron emitting chamber side of the cathode substrate. The vacuum seal member is placed covering the back of the electron emitting chamber side, and has a shell structure for receiving the atmospheric pressure.
