Patent ID: 7210978

Claim:
A method of fabricating a field emission display comprising: a step of forming at least one cathode electrode on a cathode substrate, including, screen printing a silver paste on the substrate; providing a gray-scale mask over the silver paste; exposing the silver paste with a light through the gray-scale mask, wherein the gray-scale mask has a gradually increasing transmission rate of the light from a center to a periphery thereof; and removing the portion of the silver paste that has been exposed by the light to form a first conductive layer, wherein the first conductive layer having a protruding center gradually descending towards a periphery thereof; and forming a second conductive layer on top of central region of the first conductive layer; forming a dielectric layer on the cathode substrate, wherein the dielectric layer is patterned to encompass the cathode electrode therein; forming a gate conductive layer on the dielectric layer, wherein the gate conductive layer has an aperture aligned with the cathode electrode; and a step of forming at least one anode electrode on an anode substrate over the gate conductive layer, wherein the anode electrode is aligned with the cathode electrode.
