ABSTRACT:
An FED has a cathode, an anode and an insulating supporting device. The cathode has a plurality of cathode electron emitter layers and a cathode substrate. The cathode has a plurality of cathode ribs disposed on the cathode substrate, and the cathode ribs are used for laterally separating any respective two cathode ribs. The anode has a phosphors layer and an anode substrate. The insulating supporting device is arranged between the cathode ribs and the anode, and has a reflection layer facing the anode and a gate made of a conductive material and disposed above the cathode ribs. The reflection layer is capable of reflecting light emitted from the phosphors layer.
