Abstract:
An image pickup device comprising:a pair of first and second substrates facing each other with a vacuum space interposed therebetween, the second substrate being transparent; a plurality of electron-emitting devices provided over said first substrate on a side of the vacuum space, said electron-emitting devices each comprising: an insulating layer deposited over an electron source layer which is formed over an ohmic electrode; and a metal thin film electrode deposited over said insulating layer, wherein said insulating layer and said metal thin film electrode include an island region as an electron-emitting section in which film thicknesses thereof are gradually reduced toward said electron source layer; and a photoconductive layer provided over said second substrate on a side of the vacuum space to photoelectrically convert an incident light passing through the second substrate into an electric signal.
