Abstract
A field emission type backlight device with high light efficiency may include a front substrate, a reflective substrate on the front substrate, a rear substrate separated from the front substrate by a predetermined gap, anode electrodes provided with a predetermined gap between them on the rear substrate, a light-emitting layer on the anode electrode, a cathode electrode and a gate electrode spaced apart on the rear substrate between the anode electrodes, and an electron emission source emitting electrons by electric field on the cathode electrode.
