Zusammenfassung:An electron emitting device having an electron-emitting region formed in electroconductive film is manufactured by a method that includes applying a pulse voltage across an electroconductive film in an atmosphere containing a reductive substance, for example H2, CO or organic substance. In the preferred method the pulse width T1 and spacing T2 are related as T2≥5T1. The pulse voltage amplitude may be vamped after an initial period of constancy.
