A substrate for a GIP type liquid crystal display device comprising MPS wires for inspecting lines after a cell array process is disclosed herein. The substrate comprises a mother substrate comprising a plurality of panel regions defined therein, each of the panel regions including an active area having a thin film transistor array formed therein, a dummy area and a non-display area, a plurality of TCPs disposed in the non-display area of the mother substrate; a GIP gate driver and signal lines to apply various signals to the GIP gate drivers, the GIP gate driver and signal lines being disposed in the dummy area; and a plurality of MPS wires extending from the non-display area of a first panel region to a non-display area opposite to a data pad of an adjacent panel region to inspect for defects of gate lines, data lines, common line, voltage line and the signal lines.
