Abstract:
An apparatus for producing an electron-emitting thin film substrate, comprising a stage on which a substrate on which electrode pairs arranged along plural rows and columns is mounted, and a liquid droplet supplier for supplying, per each of the electrode pairs, a droplet formed from a liquid containing ingredient constituting a thin film member conducting an electron stream according to an electric field applied between the pair of electrodes during a movement relative to the substrate or the stage. The apparatus also comprises a source that provides the liquid containing ingredient constituting the thin film member to the liquid droplet supplier.
Abstract:
An electron-emitting device comprises a pair of oppositely disposed electrodes and an electroconductive film arranged between the electrodes and including a high resistance region. The high resistance region has a deposit containing carbon as a principal ingredient. The electron-emitting device can be used for an electron source of an image-forming apparatus of the flat panel type.
