Electron source and production thereof, and image-forming apparatus and production thereof |
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. A method of testing the electrode pairs and/or the thin film for a defect and then generating an electron-emitting region so as to have no defect is available.
