Wiring line assembly for thin film transistor array substrate and a method for fabricating the same

摘要

According to one aspect of the present invention, the thin film transistor array substrate basically includes a gate line assembly based on an Ag alloy. The Ag alloy comprises Ag and at least one of alloy elements and the alloy elements each bearing a low melting point. The gate line assembly comprises a gate electrode and a gate line. A data line assembly crosses over the gate line assembly while being insulated from the gate line assembly. The data line assembly comprises a source electrode, a drain electrode and a data line. A semiconductor layer contacts the source electrode and the drain electrode. The semiconductor layer forms a thin film transistor together with the gate electrode, the source electrode and the drain electrode. A pixel electrode is connected to the drain electrode.
