Patent ID: 7456564

Claim:
A field emission display (FED) comprising: a cathode portion including row signal lines and column signal lines in a stripe form allowing matrix addressing to be carried out on a substrate, and pixels defined by the row signal lines and the column signal lines, each pixel having a field emitter and a control device which comprises two terminals connected to at least the row and column signal lines and one terminal connected to an electrode on which the field emitter is disposed, wherein the control device controls the field emitter; an anode portion having an anode electrode, and a phosphor connected to the anode electrode; and a gate portion having a metal mesh for receiving a voltage, the metal mesh having a plurality of penetrating holes, and a dielectric layer formed on at least one region of the metal mesh, wherein the gate portion is disposed between the cathode portion and the anode portion to allow the surface where the dielectric layer is formed to be faced to the cathode portion and to allow electrons emitted from the field emitter to collide with the phosphor via the penetrating holes thereof, and wherein the gate portion including the dielectric layer is separated from the electrode on which the field emitter is formed, wherein the penetrating hole in the metal mesh has at least one inclined inner wall such that the size of the penetrating hole in the metal mesh decreases as it extends towards the anode, such that electrons emitted from the field emitter are focused on the phosphor, wherein the dielectric layer is formed to cover at least the inclined inner wall of the penetrating hole in the metal mesh to prevent electrons from directly colliding with the metal mesh.
