Abstract:
1. An array substrate for an IPS-LCD device, comprising: a substrate; a gate line on the substrate; a data line perpendicular to the gate line; a thin film transistor at a crossing portion between the gate and data lines; a common line parallel to the gate line; a plurality of common electrodes extending perpendicular to the common line, the plurality of common electrodes being divided into first and second portions of respective first and second domains; a plurality of pixel electrodes arranged alternately with the plurality of common electrodes, the plurality of pixel electrodes being divided into first and second portions of the respective first and second domains; an auxiliary common electrode perpendicularly contacting each of the common electrodes; and an auxiliary pixel electrode perpendicularly contacting each of the pixel electrodes; wherein the auxiliary pixel electrode is spaced apart from the auxiliary common electrode; and the pixel electrodes are on a same layer as the auxiliary pixel electrode, wherein the plurality of common electrodes have portions that do not continue entirely across a pixel region, and wherein the portions of the common electrodes that do not continue entirely across the pixel region and the auxiliary pixel electrode form a virtual line parallel to the gate line.
