ABSTRACT:
A field emission cold cathode has a plurality of emitters in a group for each gate electrode and a serial resistance layer divided into a plurality resistance layer sections each corresponding to one of the emitters. The resistance layer is divided by a deep trench filled with an insulator layer or conductive layer forming a P-N junction between the same and the resistance layer section. A linear voltage-current characteristic is obtained by a stable resistance of the resistance layer section to prevent a short-circuit failure between the emitter and the gate electrode.
