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.
Claims25
An electron-emitting device comprising:
- a pair of electrodes;
- an electroconductive film, made of an electroconductive material other than carbon, arranged between and connected to said electrodes, said electroconductive film including a fissure;
- and
- a carbon-based deposit containing carbon as a principal ingredient, said carbon-based deposit being arranged in the fissure and on said electroconductive film and connected to the electroconductive film to form a gap within the fissure that is narrower than the fissure.
