Abstract
An electron emitting device includes a first electrode located on a substrate, an insulating layer located on the first electrode, and a second electrode located on the insulating layer. The second electrode has a first surface and a second surface, which are substantially vertical to a direction that the first electrode and the insulating layer are laminated. The first surface of the second electrode is in contact with the insulating layer. A higher potential than that applied to the second electrode is applied to the first electrode to emit an electron from the second surface.
