A thin film transistor (TFT) array and an LCD (Liquid Crystal Display) panel made therefrom where at least one of the gate lines, the source electrodes, the drain electrodes and the data lines is formed of a copper alloy having a copper portion and a metal portion doped in the copper portion. The metal portion in the copper alloy includes a metal whose heat of metal oxide formation energy is greater than that of copper. The metal may be one selected from Ti (Titanium), Cr (Chromium), Ta (Tantalum), Mo (Molybdenum), In (Indium), Sn (Tin) and Al (Aluminum). The copper alloy has a high acid resistance, a high chemical resistance, and a high tolerance for moisture. The use of the copper alloy allows formation of a low resistance interconnection of copper that has a high electrical conductivity.
