Abstract
An embodiment of a unit pixel of an in-plane switching (IPS) mode LCD device includes a plurality of pixel electrodes arranged in the unit pixel region, wherein each pixel electrode is configured to apply a pixel voltage from the data line, and a plurality of common electrodes correspondingly arranged in the unit pixel region, wherein each common electrode is configured to apply a common voltage from a common line in parallel with the data line to form electric field in conjunction with the corresponding pixel electrodes. The unit pixel region is vertically divided into over three sub-regions, at least one pixel electrode spans all sub-regions, and a bent angle of the at least one pixel electrode in a sub-region is different from the bent angle of the at least one pixel electrode in an adjacent sub-region, wherein the bent angle is measured relative to the gate line.
