Abstract:
A field-emission cathode having an emitter provided with a substrate, an emitter electrode layer, an insulating layer, a gate electrode layer, the layers being formed on the substrate in this order, needlelike projections for electron emission provided on the emitter electrode layer in a gate opening from which the insulating layer and the gate electrode layer are removed and each grown from one point in a given direction, and different projections for electron emission formed on all or part of the projections. The projections of the emitter are made of metallic particles, and thereby the manufacturing cost is lowered.
