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 has a rectifier function layer, whereby the electron emission device emits electrons when an electric field is applied between the electron-supply layer and the thin-film metal.
