Abstract
A method of manufacturing a field emission display includes: sequentially forming a cathode electrode, an insulating layer, and a gate material layer on a substrate; forming a metal sacrificial layer on an upper surface of the gate material layer; forming a through hole to expose the insulating layer in the metal sacrificial layer and the gate material layer; forming an emitter hole to expose the cathode electrode in the insulating layer exposed through the through hole; forming a gate electrode by etching the gate material layer constituting an upper wall of the emitter hole; and forming an emitter of Carbon NanoTubes (CNTs) on an upper surface of the cathode electrode located below the through hole.
