Abstract: Provided is a pulse drive-type field emission device. The pulse drive-type field emission device includes anode and cathode substrates that are spaced apart from and face each other, a cathode electrode formed on the cathode substrate, and a field emitter formed on the cathode electrode. The pulse drive-type field emission device further includes a metal mesh-type gate electrode having an opening through which electrons emitted from the field emitter pass and a power source which applies a compensated pulse wave power to the gate electrode or the cathode electrode to compensate for vibration of the gate electrode. Thus, noise from the metal mesh can be prevented without additional fabrication processes by modifying a waveform in pulse driving.
