Electron source device, method of manufacturing the same, and flat display apparatus comprising an electron source device |
摘要 |
Phosphor layers are formed on the inner surface of a face plate. An electron source device that emits electrons to excite the phosphor layers is provided on the inner surface of a base plate. The electron source device comprises an alumina substrate that has a number of small through holes. Electron-emitting material is buried in the through holes. A reference electrode is formed on the lower surface of the alumina substrate and contacts the electron-emitting material. A gate electrode is formed on the upper surface of the substrate and insulated from the electron-emitting material. The gate electrode is configured to concentrate an electron field of the electron-emitting material by virtue of an voltage applied between the reference electrode and the gate electrode, thereby to cause the electron-emitting material to emit electrons toward the phosphor layers.
