Abstract:
A method of fabricating a light source, comprising the steps of:forming a metal film used as a cathode on a lower substrate; forming a catalytic metal film on the metal film wherein the step of forming the catalytic metal film comprises the steps of: depositing the catalytic metal film; and grain boundary etching the catalytic metal film to separate the catalytic metal film into nano-sized catalytic metal particles; growing carbon nanotubes, for emission of electrons in an applied electric field, to be vertically aligned on the catalytic metal film; mounting spacers on the catalytic metal film; and mounting a transparent upper substrate having a transparent electrode having a fluorescent body on the spacers such that the fluorescent body faces the carbon nanotubes, and sealing the transparent upper substrate with the lower substrate.
