Abstract
The present disclosure relates to a manufacturing method for an electron emitting device using a graphite adhesive material. A method of preparing paste for forming a cathode of an electron emitting device includes: mixing and dispersing a nanomaterial for electron emission and a graphite filler in a solvent; drying a mixed solution in which the nanomaterial and the graphite filler are mixed; and preparing paste by mixing a graphite binder with the dried mixture.
