Title: Liquid crystal display device and manufacturing method therefor

Abstract: The present invention includes a liquid crystal display device having an oxide film having high adhesiveness to a substrate to thereby prevent oxidation of a wiring material or the like, and includes, an electrode or a terminal electrode having high conductivity, and a manufacturing method therefor. Consequently, in the present invention, a liquid crystal display device has an electrode terminal of a TFT substrate, wherein the electrode is formed on an insulator and is comprised of a conductive layer mainly consisting of copper and an oxide covering an outer part, further the oxide is a layered structure of transparent electrodes, the layered portion having ohmic contact, and the oxide mainly consists of manganese oxide.
