Abstract
A method of fabricating a nano-tube that enables shortly cutting off the nano-tube without deteriorating the same and that when the nano-tube is used as the emitter can provide an improved flat-ability of the surface of the emitter, a method of manufacturing a field-emission type cold cathode that can provide an improved flat-ability of the surface of the emitter and that resultantly can cause an emission of a uniform, stable high-emission electric current, and a method of manufacturing a display device that includes a method of fabricating a nano-tube and/or a method of manufacturing a field-emission type cold cathode. The method of fabricating a nano-tube according to the present invention includes the step of radiating ions into a nano-tube and the step of oxidizing the nano-tube.
