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

An electron emission display device comprising:

• a back substrate;
• and
• a plurality of electron emission light-emitting devices formed on said back substrate each comprising:
• an electron emission device including 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, whereby the electron emission device emits electrons when an electric field is applied between the electron-supply layer and the thin-film metal;
• and
• a fluorescent material layer formed on said thin-film metal.
