1. A method of fabricating a liquid crystal display device, comprising:

  • providing first and second substrates having a liquid crystal region, a sealant region, and an outer region;

    forming a wiring on the first substrate, wherein the wiring crosses the sealant region;

    forming an inorganic insulating film on the wiring;

    forming an organic insulating film on the inorganic insulating film, wherein a portion of the inorganic insulating film is exposed in the sealant region; and

    forming a liquid crystal layer between the first and second substrates using a sealant,wherein forming the wiring includes;

    forming a gate line and a first common line in the liquid crystal region, a gate pad lower electrode and a common pad lower electrode in the outer region, a common link connected to the common pad lower electrode and crossing the sealant region, and a gate link connecting the gate line to the gate pad lower electrode across the sealant region;

    forming a second common line on the inorganic insulating film, the second common line crossing the gate line;

    exposing a portion of the common pad lower electrode, a portion of the first common line, a portion of the second common line, and a portion of the common link when patterning the organic insulating film;

    exposing the gate pad lower electrode and the first common line when patterning the inorganic insulating film; and

    forming a gate pad upper electrode connected to the exposed gate pad lower electrode, a common pad upper electrode connected to the portion of the common pad lower electrode, a first contact electrode connected to the portion of the first common electrode and the portion of the second common lines, and a second contact electrode connected to the portion of the second common line and the portion of the common link.
