Abstract: An electronic device having an electrode made of metal that reacts easily with carbon is provided. In the electronic device, the electrode on which carbon nanotubes are deposited by a chemical vapor deposition method using a reactant gas containing carbon and oxygen, is made of a metal generating less reaction enthalpy when reacting with carbon than when reacting with oxygen. Since the electrode is made of a metal which reacts with carbon faster than oxygen, a carbonized metal layer is formed on the electrode, thereby preventing the electrode from being oxidized. Accordingly, the carbon nanotubes can be easily deposited on the electrode.

Abstract: A field emission backlight unit for a liquid crystal display (LCD) includes: a lower substrate; first electrodes and second electrodes alternately formed in parallel lines on the lower substrate; emitters disposed on at least the first electrodes; an upper substrate spaced apart from the lower substrate by a predetermined distance such that the upper and lower substrates face each other; a third electrode formed on a bottom surface of the upper substrate; and a fluorescent layer formed on the third electrode. Since the backlight unit has a triode-type field emission structure, field emission is very stable. Since the first electrodes and the second electrodes are formed in the same plane, brightness uniformity is improved and manufacturing processes are simplified. If the emitters are disposed on both the first electrodes and the second electrodes, and a cathode voltage and a gate voltage are alternately applied to the first electrodes and second electrodes, the lifespan and brightness of the emitters can be improved. The above advantages are also achieved as a result of the method of driving the backlight unit and the method of manufacturing the lower panel thereof.
