Abstract: Disclosed is an image pickup device capable of greatly reducing delay in drive signals supplied to field emission devices, and cross-talk and the like that originate in these drive signals. The image pickup device comprises a photoelectric conversion film for receiving incident light on one side thereof; a field emission layer having an electron emitting surface apart from and facing the other side of the photoelectric conversion film, and including a plurality of electron emission devices; and a drive layer formed on a back side of the field emission layer and including a plurality of device drive circuits for supplying drive signals to each of back electrodes of the plurality of electron emission devices.

Abstract: An electron-emitting device includes an electron source layer (12) made of a metal, a metal alloy or a semiconductor, an insulating layer (13) formed on the electron source layer and a metal thin film electrode (15) formed on the insulating layer. Electrons are emitted upon application of an electric field between the electron source layer and the metal thin film electrode. The insulating layer has at least one island region (14) which constitutes an electron-emitting section in which the film thickness of the insulating layer is gradually reduced. The electron-emitting device further includes a carbon region (40) made of carbon or a carbon compound on at least one of a top, bottom and inside of the island region.

Abstract: An electron emission device comprises an electron-supply layer made of metal or semiconductor and disposed on an ohmic electrode; an insulator layer formed on the electron-supply layer; and a thin-film metal electrode formed on the insulator layer. The electron-supply layer is essentially composed of elements belonging to group IV and contains an additive of at least one material selected from atomic elements belonging to group III or V.
