Abstract
A driving method of an electron emitting device which includes a first electrode, a particle layer formed on the first electrode and including insulating particles, and a second electrode formed on the particle layer includes: applying a voltage between the first and second electrodes to emit electrons from the first electrode so that the electrons are accelerated through the particle layer and emitted from the second electrode, wherein the applied voltage includes pulses which have a first frequency and are oscillated at a second frequency lower than the first frequency.
