ABSTRACT:
An electron-emitting device has a pair of device electrodes formed on a substrate, an electroconductive film connecting the device electrodes and an electron-emitting region formed in the electroconductive film. The electron-emitting device is manufactured by (1) applying an ink containing the material for producing the electroconductive film to a predetermined position of the substrate in the form of one or more than one drops by means an ink-jet apparatus, (2) drying and/or baking the applied drop(s) to turn the drop(s) into an electroconductive thin film and (3) applying a voltage to the pair of device electrodes to flow an electric current through the electroconductive film and produce an electron-emitting region. Steps (1) and (2) are so conducted that the electroconductive film formed by steps (1) and (2) have a latent image apt to produce an electron-emitting region by the Joule's heat generated by step (3).
