A field emission backlight device may include a first substrate and a second substrate separate from and roughly parallel to each other, a first anode electrode and a second anode electrode that face each other on inner surfaces of the first substrate and the second substrate, and cathode electrodes separate from and roughly parallel to one another between the first substrate and the second substrate. It may also include electron emission sources disposed on the cathode electrodes to emit electrons by an electric field and a phosphorous layer disposed on the first anode electrode or the second anode electrode.

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.
