Abstract:
An image display device for forming images by causing a phosphor layer to emit light with electrons emitted from electron-emitting elements, the image display device comprising:a vacuum container; a phosphor layer; an anode wiring contacting the phosphor layer; a substrate provided with a cathode wiring made of a patterned conductor; and electron-emitting elements made by applying, to predetermined positions of the substrate, a carbon ink made into a paste with an organic binder and a solvent, the ink comprising (i) carbon particle having a 6-membered carbon ring, and (ii) support particles for supporting the carbon particles, and firing the ink, wherein, after the firing, the support particles are decomposed, forming voids in an aggregation of the carbon particles; wherein the cathode wiring is patterned into stripes; the phosphor layer has electrically separated stripes that are arranged in a lane substantially parallel to the stripes of the cathode wiring and extend substantially perpendicular to the stripes of the cathode wiring; and the image display device is matrix-drive between the stripes of the phosphor layer and the stripes of the cathode wiring.
