A source driver performs inversion driving of data lines of a liquid crystal panel. For every two adjacent data lines, there are provided a high-side amplifier HAMP which generates a driving voltage of a first polarity and a low-side amplifier LAMP which generates a driving voltage of a second polarity opposite to the first polarity. Further, an output switch SW outputs to the two data lines LD by switching between the two driving voltages Vp, Vn that have been generated by the high-side amplifier HAMP and the low-side amplifier LAMP. The power supply terminal on the low-potential side of the high-side amplifier HAMP and the power supply terminal on the high-potential side of the low-side amplifier LAMP are connected to a common charge share capacitor C1.
