An emitter for a field emission device (FED) designed to increase durability by interposing an ultraviolet (UV) transmissive resistive layer between a substrate and an emitter and a method for fabricating the same. The method includes depositing a transparent electrode on a transparent substrate, forming a resistive layer by stacking an ultraviolet (UV) transmissive resistive material on the transparent electrode, forming an emitter layer by stacking a carbon nanotube (CNT) on the UV transmissive resistive material, and patterning the emitter layer according to a predetermined emitter pattern.

A Field Emission Device (FED) includes an emitter formed on a cathode electrode and including Carbon NanoTubes (CNTs), and a gate electrode to extract electrons from the emitter. In addition, a RuOx layer or a PdOx layer is coated on the emitter to protect the CNTs and to stabilize the emission from the CNTs. A stabilizer layer to stabilize an emission structure and to protect emission ends is coated on the surface of a CNT emitter or the surfaces of the CNTs, more specifically, the emission ends of the CNTs, in order to prevent abrasion of the CNTs caused by an excess current or an emission process.

A method for driving a field emission device (FED) applies an alternating (AC) voltage as a driving voltage for emitting electrons in a field emission device comprising cathode electrode including an emitter and an anode electrode facing the cathode electrode. A method for aging an FED uses a constant voltage so that electrons cannot be emitted from the electron emission source, and an AC voltage so that electrons can be periodically emitted from the emitter when the FED is aged.
