Abstract
Abstract A surface-conductive electron beam source having a fine particle film which is formed by repeating a film formation step of applying and calcining an organic metal compound solution several times. A pair of electrodes come in contact with the fine particle film, and an electron-emitting portion is formed at a part of the fine particle film. There is also a display device having the electron beam source, a modulation means for modulating an electron beam emitted from the electron beam source in accordance with an information signal, and an image-forming member for forming an image by the irradiation of the electron beam.
