Abstract
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.
