Abstract: A driving apparatus of a display panel permits an electric power consumption at the time of generation of a pixel data pulse can be reduced. Charges stored in a capacitor are discharged and supplied to a power line. Subsequently, a power potential is applied to the power line and, thereafter, charges stored on column electrodes of the display panel are charged into the capacitor via the power line. Finally, the power line is connected to the ground only for a short predetermined period of time. By connecting the power line and the column electrodes only for a predetermined period of time in accordance with a video signal, the pixel data pulses are applied to the column electrodes.
