ABSTRACT:
A horizontal electric field switching liquid crystal display device includes a gate line, a common line parallel to the gate line and provided at an area adjacent to the gate line, a data line crossing the gate line with a gate insulating film therebetween to define a pixel area, a thin film transistor provided adjacent to a crossing of the gate line and the data line, a common electrode provided in the pixel area and connected to the common line, a pixel electrode connected to the thin film transistor and provided in such a manner to form a horizontal electric field along with the common electrode in the pixel area on the same plane as the common electrode, a storage capacitor electrode overlapping the common electrode to provide a storage capacitor, and a contact electrode contacting the pixel electrode, the thin film transistor and the storage electrode at their side surfaces.
