TRANSPARENT ELECTROCONDUCTIVE FILM AND PROCESS FOR PRODUCING THE SAME

摘要

This invention provides a transparent electroconductive film comprising a transparent substrate and a transparent electroconductive oxide layer provided on the transparent substrate, which can solve a problem of the prior art technique that, when the transparent electroconductive oxide layer is formed of zinc oxide, the surface resistivity of the transparent electroconductive oxide layer increases with the elapse of time and difficulties have been experienced in providing a transparent electroconductive film stable against an environmental fluctuation. In the transparent electroconductive film, a hard carbon film is provided on the surface of a transparent electroconductive oxide layer having a single or multilayer structure and composed mainly of zinc oxide in "the order of transparent substrate - hard carbon film - transparent electroconductive oxide layer - hard carbon film" or "the order of hard carbon film - transparent substrate - transparent electroconductive oxide layer - hard carbon film".Alternatively, an organosilicon compound covering layer is formed on the surface of the transparent electroconductive oxide layer. According to the above constitution, the water contact angle can be brought to not less than 75 degrees, and a rise in resistance of the transparent electroconductive oxide layer can be suppressed.
