ABSTRACT:
An electron emitting device includes a pair of device electrodes disposed at locations opposite to each other, a conductive thin film in contact with both the pair of device electrodes, and an electron emitting region formed in a part of the conductive thin film. The conductive thin film is composed of fine particles including a first metal element serving as a main constituent element and at least one second metal element. The second metal element is to precipitate at the surface of the conductive thin film and thus form a low work function material layer. When a voltage is applied between the pair of device electrodes, the second metal element moves from the inside of the conductive thin film to at least a part of the surface of the conductive thin film.
