摘要： A vacuum envelope with a built-in electron source capable of preventing peeling of gate electrodes, to thereby enhance reliability in operation over a long period of time and reducing a manufacturing cost thereof. The gate electrodes each are made of niobium oxide or niobium nitride. Nb for the gate electrode is previously oxidized or nitrided to prevent progress of oxidation of the gate electrode due to release of oxygen from lead oxide contained in a seal material during heating for sealing, resulting in expansion of the gate electrode. An insulating layer is formed on a cathode substrate and the gate electrodes are formed on the insulating layer. Then, the seal material is applied onto the insulating layer so as to cover a part of each of the gate electrodes, so that the cathode substrate may be sealedly joined to an anode substrate.

摘要： A field emission element in which a cathode substrate and an anode substrate are spaced from each other and are hermetically sealed. The field emission element comprises cathode electrodes and gate terminals formed on the cathode substrate; an insulating layer overlaying the cathode electrodes and the gate electrodes, the cathode electrodes and the gate terminals being partially extracted outward from the insulating layer, gate electrodes formed on the insulating layer, wherein the gate electrodes are arranged so as to cross said cathode electrodes at intersections, openings each being formed through a cathode electrode and an insulating layer at each of the intersections, a resistance layer at least formed on a part of each of the cathode electrodes, and emitter electrodes each electrically connected to a cathode electrode via the resistance layer formed within an opening. Each of the gate electrode is electrically connected to a corresponding one of the gate terminals via a through hole formed in the insulating layer.
