Abstract

A field emitter cold cathode has a substrate possessing a first main surface on one side of itself and a second main surface on the other side of itself and has windows formed in itself. An emitter layer is formed on the first main surface side of the substrate, and has emitters disposed at the positions of the windows. A gate electrode layer is formed on the second main surface side of the substrate. In addition, openings are so formed as to enclose untouched the periphery of at least the leading end part of the emitters.
