摘要：
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 has a film thickness of 50 nm or greater. The electron-supply layer has a film thickness of 2.5 &mgr;m 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.
