To provide a method for manufacturing a field emitter electrode suitable for mass production while uniformly dispersing carbon nanotubes in an electrode by using an electric field copper foil process.

This method for manufacturing a field emitter electrode comprises steps of: providing an electrolytic solution containing metal ions to an electrolytic bath; providing carbon nanotubes and a cationic dispersant for preventing the agglomeration of the carbon nanotube particles to the electrolytic solution; and applying a predetermined voltage to a cathode drum and an insoluble anodic compartment both of which are immersed in the electrolytic solution to form a metal film containing the carbon nanotubes along the surface of the cathode drum.
