摘要： Two kinds of alternation signals, that is, an alternation signal for odd-numbered electrodes and an alternation signal for even-numbered electrodes, are input to an SEG driver. In accordance with those signals, the SEG driver reverses, at different timings, the polarity of SEG drive signals which are output to odd-numbered signal electrodes and the polarity of SEG drive signals which are output to even-numbered signal electrodes. As a result, spikes are generated before and after the timing of a polarity reversal of an alternation control signal which is input to a COM driver. Further, the SEG driver reverses, at the same timing and in different directions, the polarity of the SEG drive signals which are output to the odd-numbered signal electrodes and the polarity of the SEG drive signals which are output to the even-numbered signal electrodes. By so doing, the crosstalk due to the spikes is reduced.
