Liquid crystal display device
 A liquid crystal display device having a plurality of row electrodes to which a scanning voltage is applied; a plurality of column electrodes provided so as to cross the plurality of row electrodes, to which a display data voltage is applied; and a liquid crystal layer interposed between the plurality of row electrodes and the plurality of column electrodes, which provides a display function at intersections between the plurality of row electrodes and the plurality of column electrodes in response to a RMS value of a voltage applied between the plurality of row electrodes and the plurality of column electrodes, includes: a section for outputting a display data signal representing the display data voltage having three or more voltage levels; a compensation circuit for outputting a compensation data signal based on a RMS value difference between the display data voltage and a respective resultant display data voltage applied to the plurality of column electrodes; and a driving circuit for applying a compensation voltage to at least one of the plurality of column electrodes based on the compensation data signal.
