Abstract:
1. An FED comprising: a) a cathode substrate; b) an anode substrate spaced apart from the cathode substrate a predetermined distance forming a gap there between; c) a cathode electrode formed on the cathode substrate; d) a plurality of cathode electron emitter layers contacting the cathode electrode, wherein each of the cathode electron emitter layers is formed by one of screen-printing and spreading; e) an anode electrode formed on the anode substrate; f) a plurality of phosphor layers formed on the anode electrode, wherein each of the phosphor layers is formed by one of screen-printing and spreading; g) a plurality of cathode ribs located on the cathode substrate; h) a plurality of anode ribs located on the anode substrate; and i) an insulating supporting device located in the gap between the cathode ribs and the anode ribs, the insulating supporting device having a reflection layer formed on a top thereof reflecting light emitted from the phosphor layers and a gate conductive line formed on a bottom thereof.
