An electron emission device comprises: a first substrate and a second substrate which are positioned to face each other; cathodes formed on the first substrate; electron emitting regions electrically connected to the cathodes; an insulating layer formed on the first substrate and having openings for exposing the electron emitting regions; and gate electrodes formed on the insulating layer. The electron emitting regions include at least one porous alumina template formed on the cathodes, and the electron emitting regions are grown vertically in the porous alumina template. A method for fabricating the electron emission device includes forming a porous alumina template on the cathodes using anodic oxidation, and forming electron emitting regions by use of chemical vapor deposition while injecting a carrier gas and applying a voltage between the first substrate and the cathodes, and growing electron emitting material in the porous alumina template.
