Abstract
A method of aging a field emission device including a cathode and an anode arranged parallel to each other, an emitter arranged on the cathode to emit electrons to the anode, and a gate electrode arranged on the cathode adjacent to the emitter, the method including: supplying a voltage to the cathode; supplying a voltage to the gate; and then supplying a sufficiently low voltage to the anode so as to prevent a short-circuited portion between the cathode and the gate electrode from being permanently damaged due to an overcurrent.
