electron emission characteristics can be improved in the emitter array structure for a field emission display device having

摘要

Covering the first substrate and a plurality of gate electrodes and said gate electrode is formed to have a random pattern on the first substrate while having an arbitrary pattern on an insulating layer being formed on the first substrate, the insulating layer and a plurality of cathode electrodes is formed, and a plurality of emitters as electrical contact to the cathode electrodes disposed in the pixel region is set on the first substrate, while connected to the gate electrode and electrically connected with any of the emitters at a distance and a plurality of counter electrodes disposed on the insulating layer, as the leave the first substrate and any spacing arrangement, the first second substrate and facing the first substrate to form the substrate and the vacuum container the first comprises a fluorescent layer formed with an anode electrode and a random pattern over the anode electrode is formed on a surface of a second substrate, with the cathode electrode are portions receiving from the emitter portion thereof is removed is formed, the emitter receiving portions is formed on the cathode electrode to be placed the wall formed by the cathode electrode between them, the emitter is whisking at least disposed in the receiving portion being in contact with the cathode electrode, the counter electrode is at least a part It is formed so as to be disposed above the receiving portion in the emitter. ; Carbon nanotube field emission, FED, emitter, counter, luminance
