ABSTRACT:
A field emission cathode capable of permitting a voltage required for starting emission of electrons from the emitters to be decreased and the emission to be rendered uniform. The field emission cathode includes cathode electrodes formed on a substrate. On each of the cathode electrodes are arranged a plurality of emitters through diodes each acting as a constant-current element, and gate electrodes are arranged above the emitters. Arrangement of the diodes between the emitters and the cathode electrode permits a drive voltage to be reduced as compared with arrangement of a resistive layer therebetween, because a diode is generally decreased in voltage drop as compared with the resistive layer. Also, the arrangement renders emission of electrons from each of the emitters uniform.
