Liquid crystal display device and method of manufacturing the same

A method of manufacturing a liquid crystal display device, comprising:

• forming a gate line and a data line on a substrate crossing each other to define a pixel region;
• forming a thin film transistor in the pixel region and connected to the gate line and the data line;
• forming a pixel electrode in the pixel region and connected to the thin film transistor;
• and
• forming a gate pad at an end of the gate line and a data pad at an end of the data line, forming at least one of the gate pad and the data pad including:
• forming a pad electrode including at least one pad contact hole therein along with a passivation layer, the passivation layer on the pad electrode, the at least one pad contact hole having an asymmetric shape with respect to a vertical axis on the pad electrode;
• and
• forming a pad electrode terminal contacting inner side surfaces of the pad electrode surrounding the plurality of pad contact holes,
• wherein the asymmetric shape of the at least one pad contact hole is determined based on a contact area obtained using a circumference of the at least one pad contact hole and thickness of the pad electrode in order to reduce a contact resistance.
