ABSTRACT:
An electron emission device exhibits a high electron emission efficiency. The device includes an electron supply layer of metal or semiconductor, an insulator layer formed on the electron supply layer, and a thin-film metal electrode formed on the insulator layer. The insulator layer contains chemical elements constituting the electron supply layer and has a film thickness of 50 nm or greater. When an electric field is applied between the electron supply layer and the thin-film metal electrode, the electron emission device emits electrons.
