Abstract:
1. A Field Emission Display (FED) comprising: a first substrate; a first insulating layer arranged on the first substrate; a cathode arranged on the first substrate to cover the first insulating layer, the cathode having a first opening arranged between portions thereof covering the first insulating layer; a second insulating layer arranged on the first substrate and the cathode, the second insulating layer having a second opening connected to the first opening to expose a portion of the cathode; a gate electrode arranged on the second insulating layer, the gate electrode having a third opening connected to the second opening; a plurality of emitters arranged on the cathode in the first opening and along both edges of the first opening and spaced apart from each other; and a second substrate facing the first substrate and spaced apart therefrom and having an anode and a fluorescent layer arranged on a surface thereof: wherein the cathode comprises a cavity arranged between the plurality of emitters; and wherein a distance between the plurality of emitters is less than a width of the first opening and is greater than a width of the cavity.
