ABSTRACT:
A surface conduction electron-emitting device includes a high-potential electrode provided on a substrate surface, an electron-emitting region provided in contact with the periphery of an exposed part of the high-potential electrode, and a low-potential electrode 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 device 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.
