Abstract: A triode structure of a field emission display is manufactured with thick-film technology. The triode structure includes a cathode electrode layer that comprises a metallic catalyst. Isomeric carbon emitters can be grown on the cathode electrode layer by CVD process at a low temperature because of the metallic catalyst.

The combination of thick film technology and low temperature CVD process provide a low cost method for fabricating a large area field emission display with isomeric carbon emitters.
