Abstract
An electron emission device includes a substrate, cathode electrodes formed on the substrate, electron emission regions electrically coupled to the cathode electrodes, an insulation layer formed on the substrate while covering the cathode electrodes, and gate electrodes formed on the insulation layer and crossing the cathode electrodes. One or more gate holes are formed at each of crossing regions of the gate electrodes and the cathode electrodes through the insulation layer and the gate electrodes. At least one of the cathode electrodes includes at least two openings divided by a bridge. The at least two openings divided by the bridge are formed on each exposed region of the cathode electrodes through the gate holes. A corresponding one of the electron emission regions contacts the bridge and extends toward the walls of at least one of the openings but is spaced away from the cathode electrodes.
