Abstract
An electron source forming substrate comprises an insulating material film provided on a substrate surface, where an electron-emitting device is arranged. The insulating material film contains a metallic oxide and has a vacancy, so that the vacancy suppresses diffusion of Na from a substrate thereunder, thereby electron-emitting characteristic is maintained stable without adverse effect due to Na even after long time operation.
