Abstract: A field emission device and a method of driving the multi-electrode field emission device having a single driving power source are disclosed. The field emission device includes a cathode electrode, one or more gate electrodes, a voltage division unit, and a power source unit. The cathode electrode is figured such that at least one emitter is formed thereon. The gate electrodes are disposed between an anode electrode and the cathode electrode, and each have one or more openings through which electrons emitted from the emitter can pass. The voltage division unit has one or more divider resistors, and divides a voltage applied from the power source unit using the divider resistors and then applies partial voltages to the one or more gate electrodes. The power source unit includes a single power source, and applies the voltage to the voltage division unit.
