Abstract:
A display device comprising:a display panel having a capacitive load, and a semiconductor device having a high potential side power terminal to which a high potential is applied, a low potential side power terminal to which a low potential is applied, a power charge/discharge terminal to which a pulsed driving waveform changing between the high potential and the low potential is applied and an output terminal to which the capacitive load is connected, the semiconductor device functioning to generate an output responsive to the driving waveform to the output terminal to thereby drive the capacitive load, wherein the semiconductor device comprises a first p-channel MOS transistor having a source connected to the power charge/discharge terminal, a drain connected to the output terminal, a backgate connected to the high potential side power terminal, and a gate to which a first control signal indicating that the first p-channel MOS transistor should be turned on during an output period in which the capacitive load is to be charged and discharged is applied.
