摘要:
A thin film transistor circuit device and the production method thereof is demanded for a thin film transistor circuit device, which contains wiring having a structure of an aluminum alloy in a lower layer and a molybdenum alloy in an upper layer, wherein corrosion in air of the molybdenum alloy does not proceed easily. A thin film transistor circuit device which exposes a portion of wiring covered with an insulating film that connects thin film transistors of a main circuit region formed on a center portion of a substrate to a protection circuit region formed on an outer periphery of the substrate, which contains on the exposed surface a terminal which is formed of terminal electrode metal, wherein an uppermost surface of the wiring is a molybdenum alloy comprising niobium.
