Abstract
The present invention includes a liquid crystal display device with an oxide film having high adhesiveness to a semiconductor layer or a pixel electrode to thereby prevent oxidation of a wiring material or the like, and includes a source electrode and a drain electrode having high conductivity, and a manufacturing method therefor. In one embodiment of the present invention, a liquid crystal display device has a TFT electrode of a TFT substrate, wherein a source electrode or a drain electrode includes a layer of mainly copper and an oxide covering an outer part of the layer. Further, in the present invention, the semiconductor layer or the pixel electrode and said source electrode or the drain electrode are in ohmic contact in the TFT electrode.
