| 摘要 |
The present invention provides an electron emission device capable of deflecting emitted electrons to a predetermined direction and preferably emitting electrons with a small drive voltage as well as a production method of the same. The electron emission according to the present invention includes a layered body including an auxiliary electrode, a first insulation layer, a first gate electrode, a second insulation layer, an emitter electrode, a third insulation layer, and a second gate electrode formed in this order on a substrate. In this electron emission device, a hole is formed through the first insulation layer, the first gate electrode, the second insulation layer, the emitter electrode, the third insulation layer, and the second gate electrode, so that the auxiliary electrode is exposed at the bottom of the hole and the first gate electrode protrudes further than the emitter electrode toward the center line of the hole.
