A protected faceplate structure of a field emission display device is disclosed in one embodiment. Specifically, in one embodiment, the present invention recites a faceplate of a field emission display device wherein the faceplate of the field emission display device is adapted to have phosphor containing wells disposed above one side thereof. The present embodiment is further comprised of a barrier layer which is disposed over the one side of said faceplate which is adapted to have phosphor containing wells disposed thereabove. The barrier layer of the present embodiment is adapted to prevent degradation of the faceplate. Specifically, the barrier layer of the present embodiment is adapted to prevent degradation of the faceplate due to electron bombardment by electrons directed towards the phosphor containing wells.
A method for preventing contamination of a field emission display device, said method comprising:
A field emission display device comprising means for preventing migration of contaminants from a cathode structure into an active region of said field emission display device, said contaminants due to electron bombardment of said cathode structure, said preventing means comprising a substantially continuous and substantially non-porous barrier layer of substantially uniform thickness between said cathode structure and plurality of cathode emitters.
