Patent ID: 7616283

Claim:
An in-plane switching (IPS) mode LCD device, comprising: a plurality of gate lines and a plurality of data lines arranged on a first substrate to cross each other, thereby defining a plurality of unit pixel regions, wherein each unit pixel region is vertically divided into first, second and third sub-regions; a plurality of thin film transistors for each unit pixel arranged at each of a plurality of crossing points where the gate lines cross the data lines; a plurality of common lines arranged in parallel with the plurality of gate lines and the plurality of data lines; a plurality of common electrodes branching from each of the common lines which are parallel with the plurality of data lines, wherein each common electrode is bent in the first sub-region at a first angle, in the second sub-region at a second angle, and in the third sub-region at a third angle relative to the gate lines; a plurality of pixel electrodes connected to each thin film transistor and arranged in parallel with the plurality of common electrodes; and a liquid crystal layer arranged between the first substrate and a second substrate opposite to the first substrate, wherein the common and pixel electrodes of each unit pixel region are bent at an angle of substantially 20° in the first sub region, an angle of substantially 15° in the second sub region, and an angle of substantially 10° in the third sub region.
