Claims
- 1. 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.
- 2. The image display device of claim 1, wherein the substrate is integrated into the vacuum container.
- 3. 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; 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 particles 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; and gate electrodes arranged between the phosphor layer and the substrate; wherein the cathode wiring is patterned into stripes; the gate electrodes have electrically separated stripes that are arranged in a plane 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.
- 4. The image display device of claim 3, further comprising control electrodes between the phosphor layer and the gate electrodes, the control electrodes functioning to focus or to focus and deflect an electron beam.
- 5. The image display device of claim 3, wherein the substrate is integrated into the vacuum container.
- 6. 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 the support particles are made of powder that decomposes into a gas when heated or burned, and wherein the decomposition temperature of the support particles is lower than the decomposition temperature of the organic binder; and wherein the cathode wiring is patterned into stripes; the phosphor layer has electrically separated stripes that are arranged in plane 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-driven between the stripes of the phosphor layer and the stripes of the cathode wiring.
- 7. The image display device of claim 6, wherein the substrate is integrated into the vacuum container.
- 8. 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; 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 the support particles are made of powder that decomposes into a gas when heated or burned, and wherein the decomposition temperature of the support particles is lower than the decomposition temperature of the organic binder, and wherein the cathode wiring is patterned into stripes; and gate electrodes arranged between the phosphor layer and the substrate; wherein the cathode wiring is patterned into stripes; the gate electrodes have electrically separated stripes that are arranged in a plane 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-driven between the stripes of the phosphor layer and the stripes of the cathode wiring.
- 9. The image display device of claim 8, further comprising control electrodes between the phosphor layer and the gate electrodes, the control electrodes functioning to focus or to focus and deflect an electron beam.
- 10. The image display device of claim 8, wherein the substrate is integrated into the vacuum container.
