Patent ID: 7508125

Claim:
A Field Emission Display (FED), comprising: a first substrate; a cathode electrode arranged on the first substrate in a first direction; a cathode focusing electrode arranged on the cathode electrode and having a rectangular first aperture elongated in the first direction; an insulating layer arranged on the first substrate to cover the cathode focusing electrode and having a plurality of second apertures arranged in regions where the insulating layer overlaps the cathode electrode in a second direction perpendicular to the first direction and connected to the first aperture; a gate electrode arranged on the insulating layer to extend in the second direction and having a plurality of third apertures connected to the corresponding second apertures; an emitter arranged on the cathode electrode within the first aperture; and a second substrate arranged opposite to and spaced apart from the first substrate and having an anode electrode and a phosphor layer thereon; wherein the third aperture is elongated in the second direction so as to be longer in the second direction than in the first direction; and wherein the first aperture corresponds to each pixel, and wherein the plurality of second and third apertures are arranged for each pixel.
