ELECTRODE MATERIAL FOR ELECTRON EMISSION ELEMENT USING CARBON NANOTUBE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an electrode material for an electron emission element using carbon nanotubes and its manufacturing method suitable for mass production, profitable in cost, and capable of reducing driving voltage and fining a display screen in use as an electrode for a field emission type flat panel display.

SOLUTION: This electrode material using the carbon nanotubes for the electron emission element is formed by transferring the carbon nanotubes 11 each grown from a catalyst particle 12 serving as a core on a substrate 3 to an extensible conductive film 8 at predetermined intervals. The conductive film is formed by dispersing 5-30 wt% of particle conductors in a polymer film with a thickness of 5-2000μm.
