Abstract
A display panel has a first pixel group selected by a first scan line, and second pixel group selected by second scan line. A data line is shared by pixel in the first pixel group and a pixel in the second pixel group. In first scanning period, a driving unit in a circuit device outputs a data voltage with first polarity to the first data line, and outputs data voltage with second polarity, which is polarity opposite to the first polarity, to the second data line. In second scanning period, the driving unit outputs a data voltage with third polarity to the first data line, and outputs a data voltage with fourth polarity, which is polarity opposite to the third polarity, to the second data line. A polarity setting unit in the circuit device sets the first polarity, the second polarity, the third polarity, and the fourth polarity.
