Electron emission light-emitting device and display apparatus using the same

摘要

An electron emission light-emitting device comprises an electron emission device and a fluorescent material layer formed on the thin-film metal. The electron emission device comprises an electron-supply layer made of semiconductor formed 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 emission light-emitting device emits light when an electric field is applied between the electron-supply layer and the thin-film metal.
