摘要：
An electron source is constituted of a substrate, and an electron-emitting element provided on the substrate. The electron-emitting element comprises a plurality of electrode pairs having an electroconductive film between each of the electrode pairs. An electron-emitting region is formed on the electroconductive film of selected ones of the electrode pairs.
