There is provided a display device composed of a display panel having a capacitive load such as an ELDP and a PDP and a semiconductor device for driving the capacitive load which can reliably operate, collect substantially all the power charged to the capacitive load irrespective of the current amplification factor of a parasitic bipolar transistor. The semiconductor device has a high potential side power terminal, low potential side power terminal, power charge/discharge terminal and an output terminal to which a capacitive load is connected. The semiconductor device also includes a first p-channel MOS transistor in which the source is connected to the power charge/discharge terminal, the drain is connected to the output terminal and the backgate is connected to the high potential side power terminal and a first control signal C1 indicating that the first P-channel MOS transistor should be in ON state during an output period is applied to a gate.
