Electron source substrate with high-impedance portion, and image-forming apparatus |
摘要 |
An electron source substrate including: a substrate; an electron-emitting device having a pair of device electrodes locating on the substrate and an electroconductive thin film which is provided between the device electrodes and has an electron-emitting region; and an antistatic film which is come into contact with at least the pair of device electrodes and covers over an exposed surface of the substrate, wherein a leakage current flowing between the device electrodes in a non-driving mode at a low voltage is suppressed. A high-impedance portion which obstructs the current caused across the pair of device electrodes through the antistatic film is provided in the antistatic film. |
