Abstract
A method of manufacturing a cold cathode type electron emitting device includes forming a pair of electrodes, which are spaced from each other, on a substrate, forming conductive thin films, which are electrically connected with the pair of electrodes and have a cracked portion therebetween, on a space between the pair of electrodes, forming conductive deposits on the cracked portion of the conductive thin films to form an electron emission section, and subjecting the electron emission section to a treatment using plasma to expand a gap between the conductive deposits on the cracked portion.
