Thin film transistor substrate of a horizontal electric field type LCD and fabricating method thereof

A thin film transistor substrate of a horizontal electric field type LCD, comprising:

• a substrate;
• a gate line and a common line disposed on the substrate and arranged parallel with each other;
• a data line disposed on the substrate intersecting with the gate line and the common line, the data line insulated from the gate line and the common line by a gate insulating film therebetween, a pixel area being defined by the intersection of the data line with the gate line;
• a thin film transistor disposed at the intersection of the data line and the gate line, and connected to the gate line and the data line;
• a common electrode disposed having a portion extended into the pixel area and connected to the common line;
• a pixel electrode disposed having a portion extended into the pixel area and connected to the thin film transistor, wherein a horizontal electric field is formed by the pixel electrode and the common electrode;
• a protective film disposed over the common electrode, pixel electrode, data line common line, and the thin film transistor;
• first to fourth contact holes and a plurality of stripper penetration paths provided on the substrate;
• a gate pad including a lower gate pad electrode connected to the gate line and an upper gate pad electrode disposed within a first contact hole defined through the protective film to contact the lower gate pad electrode such that the upper gate pad electrode is absent from the upper surface of the protective film;
• a common pad including a lower common pad electrode connected to the common line and an upper common pad electrode disposed within a second contact hole defined through the protective film to contact the lower common pad electrode such that the upper common pad electrode is absent from the upper surface of the protective film;
• a data pad including a lower data pad electrode connected to the data line and an upper data pad electrode disposed within a third contact hole defined through the protective film to contact the lower data pad electrode such that the upper data pad electrode is absent from the upper surface of the protective film;
• a contact electrode disposed within a fourth contact hole defined through the protective film to contact a portion of the pixel electrode and a portion of a drain electrode such that the contact electrode is absent from the upper surface of the protective film;
• and
• a plurality of dummy transparent conductive pattern disposed within the plurality of stripper penetration paths defined through the protective film such that the plurality of dummy transparent conductive pattern are absent from the upper surface of the protective film.
