Abstract:
1. A method of fabricating a field emission backlight device having: a first substrate and a second substrate that is spaced apart 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, respectively; filament wires separate from and roughly parallel to one another between the first substrate and the second substrate; carbon nanotube catalytic metal films disposed on circumferences of the filament wires; carbon nanotubes disposed on the catalytic metal films to emit electrons by an electric field; and a phosphorous layer disposed on the first anode electrode or the second anode electrode, the method comprising: dipping the filament wires in carbon nanotube catalytic metal solution to form the carbon nanotube catalytic metal films on surfaces of the filament wires; disposing the filament wires having the carbon nanotube catalytic metal films between the first substrate and the second substrate and substantially parallel to one another; sealing the first substrate and the second substrate at their outer brinks to form an internal space between the first substrate and the second substrate; applying a predetermined voltage to the filament wires to heat the filament wires; and introducing carbon-containing gas into the internal space to grow the carbon nanotube from the carbon nanotube catalytic metal film.
