Abstract
An antistatic film installed in an airtight vessel containing an electron source of an electron-generating device such as a picture display unit has a structure comprising an image of conductor or semiconductor particles with particle diameters of 0.5 to 10 nm dispersed in a medium containing a nitride, an oxide or both; and thereby improves controllability for a resistivity value, stability and reproducibility, and the adequate temperature characteristics of resistance.
