Abstract: An array substrate for use in an IPS-LCD device includes a gate electrode, a gate line, a common line, and a plurality of common electrodes that have zigzag shapes on a substrate. A gate insulation layer is formed over an entire surface of tha substrate, and an active layer and ohmic contact layers are formed in series on the gate insulation layer and over the gate electrode. Over the gate electrode and on the ohmic contact layers, source and drain electrodes are formed. At this time, a data line is formed on the gate insulation layer. A passivation layer covers an entire surface of the substrate and has a drain contact hole that expose a portion of the drain contact hole. On the passivation layer, a plurality of pixel electrodes are formed in substantially zigzag or bent shapes. These pixel electrodes correspond to the common electrodes and are spaced apart from each other. The common and pixel electrodes have a plurality of bend portions and each bend portion has an inner part that is filled with a conductive material. Since this bend portion controls a rotational direction of liquid crystal molecules, the IPS-LCD device of the present invention has a wide viewing angle and prevents the color-shift and the brightness deterioration.

The drain electrode has a drain protrusion which is positioned over the gate electrode and the slanted corner of the gate electrode and located inside the U-shaped source electrode. The drain protrusion is spaced apart from the U-shaped source electrode to form a channel region therebetween. An imaginary axis of the U-shaped source electrode and drain protrusion forms an angle with the gate line. A pixel electrode contacts the drain electrode.
