An array substrate for an in-plane switching mode liquid crystal display device includes a gate line on a substrate including a pixel region, the pixel region including a first domain at a lower side with respect to the gate line and a second domain at an upper side with respect to the gate line; a data line crossing the gate line; a thin film transistor in the pixel region and at a crossing portion of the gate and data lines; a plurality of first pixel electrodes in the first domain; a plurality of second pixel electrodes in the second domain, the plurality of first pixel electrodes and plurality of second pixel electrodes sharing the thin film transistor; a plurality of first common electrodes in the first domain and alternately arranged with the plurality of first pixel electrodes; and a plurality of second common electrodes in the second domain and alternately arranged with the plurality of second pixel electrodes.
