We have developed a surface conduction electron emitter (SCE) for next‐generation flat displays. PdO thin films (approximately 10 nm) produced by the ink‐jet process were used for forming the surface conduction electron emitter. The films were electroformed and activated while a certain voltage was applied, and an electron emitter with good characteristics was obtained. A current density of approximately 30 mA/cm 2 was attained when an anode voltage of 10 kV was applied. We confirmed operation for 60,000 hours by an acceleration test at a current density of 3 mA/cm 2 . This current density is required for “good brightness” on the surface conduction electron emitter display (SED).
