Abstract: The present invention relates to a cathode for use in a field emission device. In a triode-type cathode for use in an electron emission device being a core component constituting a field emission device, the present invention includes forming a catalytic layer at the sidewall of a gate hole and then growing an emitter in the catalytic layer, thus uniformly distributing an electric field generated by a voltage applied to a gate electrode over the emitter. Therefore, the present invention can improve the brightness contrast at a low anode voltage and also can control electrons emitted from the emitter only with the gate voltage.
