Abstract
A field emission display device and a method of fabricating the same are provided. The field emission display device may include a substrate, a transparent cathode layer, an insulation layer, a gate electrode, a resistance layer, and carbon nanotubes. The transparent cathode layer is deposited on the substrate. The insulation layer is formed on the cathode layer and has a well exposing the cathode layer. The gate electrode is formed on the insulation layer and has an opening corresponding to the well. The resistance layer is formed to surround the surface of the gate electrode and the inner walls of the opening and the well so as to block ultraviolet rays. The carbon nanotube field emitting source is positioned on the exposed cathode layer.
