Abstract
Featured is an image forming device for driving field emission electron sources capable of low-vacuum operation, high in ion impact resistance, and controlled in orientation, under X-Y addressing through electrode lines of simple and low-cost configuration. The image forming device includes cathode electrode lines and gate electrode lines of wire structure, where the field emission electron sources are selectively grown on the cathode electrode lines. A vacuum gap is provided between a supporting substrate on the back-plate side and the cathode electrode lines, and a getter is arranged on the supporting substrate.
