Abstract:
An electron-emitting element, to which a carbon ink is applied at predetermined positions of a conductor that has been patterned on a substrate, and fired,wherein the carbon ink is made into a paste with an organic binder and a solvent, and the carbon ink comprises: carbon particles including a 6-membered carbon ring; and support particles for supporting the carbon particles, wherein the support particles are made of self-combustible powder that decomposes into a gas when heated or burned or of a thermally decomposing foaming agent powder, and wherein the carbon particles comprise at least one of the group consisting of carbon nanotubes, graphite, and carbon fibers made into graphite powder, and wherein, after the firing, all of the support particles are decomposed, thereby, in an aggregation of the carbon particles, voids have been formed.
