<P>PROBLEM TO BE SOLVED: To provide an electron emission source, an electronic device using the same, and a method of manufacturing an electron emission source. <P>SOLUTION: This electron emission source includes a substrate, a cathode manufactured separately from the substrate, and the cathode includes a needle-shaped electron emission substance, e.g., carbon nanotube layer, fixed by an adhesive layer. The carbon nanotube layer is formed by using a suspension filtering method, and electron emission density is increased by a succeeding surface treatment on the electron emission substance layer. <P>COPYRIGHT: (C)2009,JPO&INPIT |
