This invention describes the new structure of a field emission cathode based flat panel display that comprises a main space and an attached auxiliary space, whose volume is larger than that of the main space. In this structure evacuation of the volume of the FED can be carried out more easily. Also getters to eliminate a build up of pressure after sealing off process can be included in the auxiliary tank and high vacuum can be maintained for the lifetime of the FED.
