Emissive flat panel display device

摘要

An emissive flat panel display device has an electron emission and control structure which uses carbon nanotubes or the like as electron sources and is formed using a relatively inexpensive manufacturing technique. Cathode electrodes, an insulation layer and gate electrodes are formed on a back substrate by screen printing. Insulation-layer openings are formed in the insulation layer and control apertures are formed in the gate electrodes at the same positions as the insulation-layer apertures. Inner peripheries of the control apertures are retracted from inner peripheries of the insulation-layer apertures formed in the insulation layer, thus preventing sagging of a silver paste for gate electrodes into the insulation-layer apertures in a step for forming the gate electrodes. Ink containing carbon nanotubes is applied to the control apertures formed in the gate electrodes by an ink jet method or the like.
