Zusammenfassung:	A common voltage driving circuit of an in-plane switching (IPS) mode liquid crystal display (LCD) device includes a first common voltage output part for swinging and outputting positive (+) and negative (−) common voltages on odd numbered common lines, a second common voltage output part for swinging and outputting negative (−) and positive (+) common voltages on even numbered common lines, an intermediate level output part for outputting an intermediate level voltage between the positive (+) and negative (−) common voltages output from the first and second common voltage output parts, a first switching part for selecting one out of the voltages output from the first common voltage output part and the intermediate level output part, and outputting the selected one, and a second switching part for selecting one out of the voltages output from the second common voltage output part and the intermediate level output part, and outputting the selected one.
