Electron emitting apparatus, manufacturing method therefor and method of operating electron emitting apparatus |
摘要 |
An electron emitting apparatus having excellent mechanical strength and capable of satisfactorily emitting electrons even if a high electric field is applied and a manufacturing method therefor are disclosed. The electron emitting apparatus according to the present invention incorporates a first gate electrode formed on a substrate, a cathode formed on the first gate electrode through a first insulating layer and having a projection projecting over the first insulating layer and a second gate electrode formed on the cathode through a second insulating layer. The electron emitting apparatus has the cathode structured such that the projection has an inclined surface, the thickness of which is reduced toward the leading end.
