The present invention discloses a field emission device, a field emission display device and a method of manufacturing the same. The disclosed field emission device includes a glass substrate, an emitter electrode formed on the glass substrate, a CNT emitter formed on the emitter electrode, a CNT emitter formed around the CNT emitter, and extracts an electron beam from the CNT emitter, And a gate stack that focuses the extracted electron beam to a given position. The gate stack includes a mask layer covering the emitter electrode around the CNT emitter, a gate insulating film formed at a predetermined height on the mask layer, a mirror electrode formed on an inclined surface of the gate insulating film, and an upper portion of the gate insulating film. And a gate electrode spaced apart from the mirror electrode, and a focus gate insulating layer and a focus gate electrode sequentially formed on the gate electrode. |
