发明名称 Electron emission device with electron-emitting fine particles comprised of a metal nucleus, a carbon coating, and a low-work-function utilizing this electron emission device
摘要 An electron emission device can be driven with a low voltage and has an excellent mass production capability. A display device, such as a color flat panel or the like, which uses such electron emission devices has an excellent display quality. The electron emission device includes a first electrode, on which a plurality of fine particles of an electron emission body obtained by terminating carbon bodies formed on metal fine particles, serving as nuclei, with a low-work-function material via oxygen are partially arranged, on a first substrate, and a second electrode where a voltage for drawing electrons from the electron emission body into a vacuum is applied. A metal of the metal fine particles is a catalytic metal. The catalytic metal is an iron-family element, such as Ni, Co, Fe or the like, or a platinum-family element, such as Pd, Ir or Pt. The carbon bodies are made of graphite. The low-work-function material is an alkaline metal or an alkaline earth metal.
