Abstract:
A driving method of an image display apparatus includes the steps of: applying a non-selection potential to a first scanning wiring; and applying a selection potential to the first scanning wiring. A voltage applied to an electron-emitting device connected to the first scanning wiring is set to a voltage having a polarity reverse to that of a voltage to be applied upon emitting electrons during at least partial period of a period when the non-selection potential is applied to the first scanning wiring. The voltage applied to the electron-emitting device connected to the first scanning wiring is set to zero volt or to a voltage having a polarity same as that of the voltage to be applied upon emitting electrons and less than the threshold voltage, during a predetermined period before the selection potential is applied to the first scanning wiring.
