Electron emitting device, electron source, and image forming apparatus |
摘要 |
<p>An electron emitting device includes a first electrode located on a substrate (1), an insulating layer located on the first electrode (2), and a second electrode (3) located on the insulating layer. Various examples are described. In one example, 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. <IMAGE></p> |
