An electron emission device, a method of manufacturing the electron emission device, and an electron emission display having the electron emission device are provided. The electron emission device includes: a first substrate; at least one sub-electrode in the first substrate; at least one cathode electrode, the at least one cathode electrode being on the first substrate and substantially covering the sub-electrode; at least one electron emission region on the cathode electrode; a first insulation layer, the first insulation layer being on the first substrate, substantially covering the cathode electrode and having at least one opening corresponding to the electron emission region; and at least one gate electrode, the at least one gate electrode being on the first insulation layer and having at least one opening corresponding to the electron emission region.
