Abstract:
A field emission element comprising:a cathode substrate and an anode substrate, said cathode and anode substrates being spaced from each other and are hermetically sealed,cathode electrodes formed on said cathode substrate;gate terminals formed on said cathode substrate;an insulating layer overlaying said cathode electrodes and said gate terminals, said cathode electrodes and said gate terminals being partially extracted outward from said insulating layer;gate electrodes formed on said insulating layer; said gate electrodes being arranged so as to cross said cathode electrodes;openings formed on said gate electrodes and said insulating layer at each intersection of said gate electrodes and said cathode electrodes;a resistance layer formed on a part of each of said cathode electrodes;emitter electrodes formed in said openings, each emitter electrode being electrically connected to said cathode electrode via said resistance layer; andthrough-holes formed on said insulating layer; wherein each of said gate electrodes is electrically connected to a corresponding one of said terminals via one of said through holes.
