A display device having a driver that drives load lines in an electro-optical panel through capacitor charge redistribution is provided with a first driving capacitance circuit that drives the load lines, and a second driving capacitance circuit that drives output of a D/A conversion circuit for outputting a voltage corresponding to a driving voltage. Settling time of the output of the D/A conversion circuit is shortened by controlling the second driving capacitance circuit to set the output of the D/A conversion circuit to a desired output voltage.
