Patent ID: 8199301

Claim:
A horizontal electric field switching liquid crystal display device, comprising: 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 plurality of pixel electrodes 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 first storage electrode extending from a drain electrode of the thin film transistor and overlapping the common line to provide a first storage capacitor; a second storage electrode overlapping the common electrode to provide a second storage capacitor; a protective layer disposed over the thin film transistor, the data line, and the gate insulating film with first and second contact holes defined through the protective layer and the gate insulating film such that the first contact hole exposes side surfaces of the first storage electrode and a first pixel electrode of the pixel electrodes and such that the second contact hole exposes side surfaces of the second storage electrode and the first pixel electrode; a first contact electrode disposed in the first contract hole contacting the first pixel electrode first storage electrode at their side surfaces; and a second contact electrode disposed in the second contact hole contacting the first pixel electrode and the second storage electrode at their side surfaces.
