Patent ID: 7365820

Claim:
An In-Plane Switching mode liquid crystal display device, comprising: a unit pixel region bordered by first and second common electrode lines extending along a first direction, and bordered by a pair of adjacent data lines extending along a second direction perpendicular to the first direction; a gate line extending through a middle region of the unit pixel region to define first and second pixel regions, the first and second common electrode lines spaced apart from the gate line by a first distance along the second direction, and the gate line crossing the pair of adjacent data lines at first and second edges of the middle region of the unit pixel region; a thin film transistor formed at the first edge of the middle region of the unit pixel region, the thin film transistor including first and second drain electrodes, a source electrode, and a gate electrode; first and second circular pixel electrodes, the first circular pixel electrode disposed within the first pixel region of the unit pixel region and electrically connected to the first drain electrode of the thin film transistor and the second circular pixel electrode disposed within the second pixel region of the unit pixel region and electrically connected to the second drain electrode of the thin film transistor; first and second circular common electrodes connected to the first common line and disposed within the first pixel region, the first circular common electrode disposed at an interior center region of the first circular pixel electrode and the second circular common electrode disposed at an exterior lateral portion of the first circular pixel electrode; and third and fourth circular common electrodes connected to the second common line and disposed within the second pixel region, the third circular common electrode disposed at an interior center region of the second circular pixel electrode and the fourth circular common electrode disposed at an exterior lateral portion of the second circular pixel electrode.
