Abstract:
An image display device comprising, in a vacuum container whose interior is kept under vacuum:a fluorescent layer; an electron emission source having an electron source; and electrodes to control electron beams emitted from the electron emission source, wherein the electron beams illuminate the fluorescent layer, and one of the electrodes, which is arranged between the fluorescent layer and the electron emission source and functions to deflect the electron beams, comprises a first plurality of wires, a second plurality of wires and a frame of a resilient material, the frame comprising two opposing sides, the two sides being flat plates that are arranged to be substantially parallel to the fluorescent layer; the first plurality of wires is strung with a certain tensile force on the flat plates by using resilience of the flat plates so as to be included in one surface substantially parallel to the fluorescent layer, the second plurality of wires is strung with a certain tensile force on the flat plates by using resilience of the flat plates so as to be included in one surface substantially parallel to the fluorescent layer, the first plurality of wires and the second plurality of wires are parallel to each other, the first plurality of wires is applied with a first potential while the second plurality of wires is applied with a second potential different from the first potential in order to deflect the electron beams passing between the first wires and the second wires in a predetermined direction according to a difference between the first potential and the second potential so that the electron beams land at desired positions on the fluorescent layer.
