Disclosed is a field emission display wherein the driving voltage can be controlled so that the electrons emitted from an emitter and drifting to an anode electrode (anode current) is regulated to a desired amount. Also disclosed is a method for controlling such a field emission display. The field emission display comprises a gate electrode (3), an emitter (2) which emits electrons by means of the driving voltage applied between itself and the gate electrode (3), an anode electrode (5) having a phosphor (6) which emits light by accepting electrons emitted from the emitter (2), a current- sensing unit (11) for sensing an anode current flowing through the anode electrode (5) and a driving voltage-controlling unit (12) for controlling the driving voltage applied between the gate electrode (3) and the emitter (2) according to the anode current sensed by the current-sensing unit (11).
