Abstract:
An electron-emitting apparatus comprising an anode electrode and an electron-emitting device disposed on a substrate, said anode electrode being disposed above said electron-emitting device, and said electron-emitting device including:first and second electrodes disposed on said substrate, which are opposite to each other;a conductive film connected to said first and second electrodes and having an electron-emitting portion including a fissure; anda field correction electrode disposed on said substrate and spaced from said first and second electrodes, wherein said second electrode is disposed between said first electrode and said field correction electrode, a lower potential is applied to one of said first and second electrodes and a higher potential to the other of said first and second electrodes, and capable of causing a singular point of an electric field, said singular point being generated by application of voltage between said first and second electrodes and application of a potential higher than those applied to the first and second electrode to said anode electrode, to approach said fissure by independently applying to said field correction electrode a field-correcting potential, said field-correcting potential being higher than said lower potential.
