COLD CATHODE ELECTRON SOURCE AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2011/046224

A1

Provided are a cold cathode electron source wherein raising and immobilization of an electron emission material are improved and electrons can be efficiently emitted, and a method for producing same. An electron emission material, an organic binder, a glass frit, and a paste for electron field emission which contains a blowing agent, are employed, wherein the electron emission material is raised by foam generated by the blowing agent, and the glass frit is melted, by heating thereof, in accordance with the generation of foam, so that the raised electron emission material is immobilized by the melted glass frit.
