Abstract
The present invention relates to the formation, on a substrate having a display area and a peripheral area, of a gate wire including a plurality of gate lines and gate electrodes in a display area and gate pads in the peripheral area, and of a common wire, including a common signal line and a plurality of common electrodes in the display area. The substrate is fabricated by using less number of steps of photo masks. A photo mask having multiple thickness is used for a photolithography step with less number of masks.
