Abstract A white light source using carbon nanotubes and a method of fabricating the same are provided. The white light source includes a metal film which is used as a cathode and formed on a lower substrate, a conductive polymer film pattern formed on the metal film, carbon nanotubes which are substantially vertically bound with the conductive polymer film pattern such that one end thereof is exposed above the surface of the conductive polymer film pattern, for emitting electrons, spacers installed on the metal film, and a transparent upper substrate which has a transparent electrode, to which a fluorescent body is attached, and is mounted on the spacers such that the fluorescent body faces the carbon nanotubes.
