Liquid crystal display device having the same openings and manufacturing method thereof

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

• forming a gate line and a first common electrode, which includes first and second horizontal common electrode bars and a plurality of first vertical common electrode bars, on a substrate;
• forming an gate insulation film on the substrate including the gate line;
• forming a semiconductor layer on the gate insulation film opposite to the gate line;
• forming a data line and source/drain electrodes on the substrate including the semiconductor layer;
• forming a passivation film, which includes a contact hole exposing the second horizontal common electrode bar, on the substrate including the data line;
• and
• forming a pixel electrode, which includes a horizontal pixel electrode bar and a plurality of vertical pixel electrode bars, and a second common electrode which includes a third horizontal common electrode bar and a plurality of second vertical common electrode bars alternately arranged with the plurality of vertical pixel electrode bars, on the passivation film,
• wherein an entire region of the second horizontal electrode bar of the first common electrode overlap the third horizontal electrode bar of the second common electrode,
• wherein the third horizontal electrode bar of the second common electrode and the horizontal pixel electrode bar of the pixel electrode are disposed on the same layer,
• wherein the outermost first vertical common electrode bars of the first common electrode overlap the corresponding outermost vertical pixel electrode bars of the pixel electrode, respectively to form a storage capacitor, and
• wherein the remaining first vertical common electrode bars of the first common electrode between the outermost first vertical common electrode bars each entirely overlap with each corresponding one of the second vertical common electrode bars of the second common electrode along a lengthwise direction of the second vertical common electrode bars.
