Transparent thin-film electrode

摘要

Provided is a transparent thin-film electrode characterized in that light transmitted through the transparent thin-film electrode is polarized. The transparent thin-film electrode comprises a conductive polymer or the transparent thin-film electrode comprises a carbon nanotube. Consequently, the transparent thin-film electrode and a liquid crystal display device or a light-emitting element using the same which has industrially satisfactory performance can be provided without using indium that has a problem in terms of stable supply and cost because the amount of indium as a resource is small and the price thereof rises sharply due to stringent demand.
