Manufacturing method of electron emitting device, electron source and image display apparatus |
摘要 |
In an electron-emitting device having a pair of electroconductors arranged on a substrate at an interval, a top of one electroconductor is higher than that of the other electroconductor and a groove extending from the interval region toward a position under a region where the one electroconductor is come into contact with the substrate is formed on the substrate. Deterioration of the electron-emitting device due to collision of charged particles is suppressed by the asymmetrical electron-emitting region, electron-emitting efficiency is improved, and a long life is realized.
