Abstract

The present invention provides an image display capable of reducing power used up or consumed by a thin-film electron-emitter matrix. As a typical one, there is provided an image display which comprises a display device including a first plate which has a plurality of electron-emitter elements each having a structure comprised of a base electrode, an insulating layer and a top electrode stacked on one another in this order, the electron-emitter element emitting electrons from the surface of the top electrode when a voltage of positive polarity is applied to the top electrode; a plurality of first electrodes for respectively applying driving voltages to the base electrodes of the electron-emitter elements lying in a row direction, of the plurality of electron-emitter elements; and a plurality of second electrodes for respectively applying driving voltages to the top electrodes of the electron-emitter elements lying in a column direction, of the plurality of electron-emitter elements, a frame component, and a second plate having phosphors, wherein a space surrounded by the first plate, the frame component and the second plate is brought into vacuum. In the image display, the first electrode and/or the second electrode held in a non-selected state is set to a high-impedance state.
