Patent ID: 7502086

Claim:
An IPS mode LCD device, comprising: a gate line and a data line crossing each other on a first substrate to define a unit pixel region; a thin film transistor at a crossing point of the gate line and the data line; a common electrode including a plurality of first segments and a plurality of second segments to define a plurality of blocks, wherein the plurality of first segments are formed substantially parallel to the gate line in the pixel region, and the plurality of second segments are formed substantially parallel to the data line and connected to the first segments; a pixel electrode including a plurality of third segments and at least one fourth segment, and being connected with a drain electrode of the thin film transistor, wherein each of the third segments is positioned between the first segments, and the least one fourth segment includes one segment connecting end parts of two adjacent third segments and being partially overlapped with the second segments of the common electrode to form a closed loop; and a common line connecting the common electrodes of adjacent pixel regions.
