PURPOSE: A method for manufacturing an electron emitter is provided to form a metal nano-particle by forming a graphen/metal nano-particle electron emitter by using a filtration process and to improve low voltage driving and field emission characteristics. CONSTITUTION: Oxide graphen diffusion solution of large size is manufactured from graphite flake of a power type. Oxide graphen/metal precursor diffusion solution is manufactured by mixing a metal precursor in the oxide graphen diffusion solution. A metal nano-particle is uniformly formed on the surface of graphen by resolving the oxide graphen/metal precursor diffusion solution through a wet process. Graphen/metal nano-particle diffusion solution is manufactured. A graphen/metal nano-particle film is formed by passing the graphen/metal nano-particle diffusion solution through a filter. The graphen/metal nano-particle film is separated from the filter and is transferred to a substrate. An electron emitter is formed.
