Abstract

The invention relates to a method for producing a field emission display (FED) that includes a first substrate with electrodes of an anode structure and a luminescent material that at least partly covers these electrodes. The electrodes of a cathode structure are affixed on a second substrate and include field emitters. The anode structure and the cathode structure are aligned with one another and interconnected in spaced-apart disposition in a gas-tight manner along their lateral edges, except for a gas inlet opening and a gas outlet opening. The field emitters are deposited by heating only the electrodes of the cathode structure while flowing a carrier gas through the gas inlet opening and the gas outlet opening.
