ABSTRACT:
A vacuum container capable of arranging a getter member therein while preventing an increase in overall height of an envelope and therefore the vacuum container. An anode substrate on which anode electrodes providing a display section are formed and a cathode substrate on which field emission cathodes are formed are arranged opposite to each other and sealedly joined to each other through an outer periphery thereof, to thereby provide an envelope. The cathode substrate is formed with a through-hole communicating with an interior of the envelope. The through-hole has a getter member received therein. The cathode substrate is provided on a portion of an outer surface thereof at which the through-hole is formed with an evacuation pipe through which the envelope is evacuated.
