Abstract: Rather than forming a data line continuously extending in one layer of a thin film transistor substrate, spaced apart segments of a first data connection pattern are formed in a same first layer as that of the gate lines but extending in a crossing direction. Spaced apart parts of a second data connection pattern are formed in a same second layer as that of the source electrodes of the substrate and also extending in the crossing direction. The segments of the first data connection pattern are connected to successive parts of the second data connection pattern to form completed data lines. In one embodiment, the gate lines of the first layer and the spaced apart segments of a first data connection pattern include a low resistivity metal such as copper.
