MANUFACTURING METHOD OF ELECTRON SOURCE, AND ELECTRON SOURCE MANUFACTURED BY THE MANUFACTURING METHOD AS WELL AS IMAGE FORMING DEVICE USING THE ELECTRON SOURCE

摘要

PROBLEM TO BE SOLVED: To eliminate creep voltage and current to a thin film for electron emission part formation during forming, and reduce the distribution of forming voltage or electric power due to a potential drop in wiring. SOLUTION: In a manufacturing method of an electron source having plural surface conduction electron emission elements arranged on a substrate, conductivity forming is carried out for the plural surface conduction electron emission elements by dividing them in plural groups electrically opened, and electrical connections are made among respective groups after the conductivity forming process which is carried out for these respective groups.
