Surface conduction electron-emitting device.

摘要

A surface conduction electron-emitting device is provided which comprises a high-potential electrode (1) provided on a substrate surface, an electron-emitting region (4, 4a, 4b) provided in contact with the periphery of an exposed part of the high-potential electrode, and a low-potential electrode (2a, 2b) further provided in contact with the periphery of the electron-emitting region. The low-potential electrode may project upward in the thickness direction of the substrate to a higher level than the high-potential electrode. A means for applying a voltage may further provided between the high-potential electrode and low-potential electrode. The low-potential electrode may be divided into plural numbers and potential may be applied to each of the low-potential electrodes independently.
