ABSTRACT:
The field emission device includes: a front substrate and a rear substrate which are disposed at a certain distance and opposite to each other; at least one or more cathode electrodes formed on the rear substrate; at least one or more gate electrodes formed to be distant from the cathode electrodes and to be insulated with the rear substrate; emitters formed on the upper surfaces of the cathode electrodes; an anode electrode formed on the front substrate toward the rear substrate side; a fluorescent layer formed on the anode electrode; a first voltage application circuit for applying an AC voltage to the anode electrode; and a second voltage application circuit for applying an AC voltage to the gate electrode, wherein the AC voltages being applied to the anode electrode and the gate electrode are synchronized.
