Abstract
A cold cathode electron source element having a cold cathode on a substrate. The cold cathode has dispersed in a cold cathode base particles of a conductive material having a lower work function than the base and a particle size which is sufficiently smaller than the thickness of the cold cathode. The element can be driven with a low voltage to induce high emission current in a stable manner. The cold cathode is easily processable. The element can have an increased surface area.
