Abstract: In a thermionic emission device for use in an electron gun assembly of a cathode ray tube, the thermionic emission device is comprised by a pair of conductive supporting members extending through an insulator substrate and a cathode member supported by the supporting members. The cathode member comprises a flat heater coated with thermion emissive substance and a pair of lead members extending in a direction perpendicular to the plane of the heater and connected between the heater and the supporting members.
