A liquid crystal display panel includes a driver having pairs of first and second D/A converters, corresponding pairs of first and second polarity changeover switches, and plural switching elements. Each of the first D/A converters receives a picture signal and outputs a positive-polarity voltage and each of the second D/A converters receives the picture signal and outputs a negative-polarity voltage. The first polarity changeover switches are connected to the outputs of the first and second D/A converters and alternately output the positive and negative polarity voltages. The second polarity changeover switches are also connected to the outputs of the first and second D/A converters and output a reverse polarity voltages. The switching elements are connected between the outputs of the first D/A converters and the first polarity switch and the output of the second D/A converters and the second polarity changeover switch. The switching elements are actuated until the voltages at the outputs of the first and second D/A converters become substantially equal.
