Abstract
There is provided a drive circuit of a display device using a capacitive load which includes a clamp circuit connected to a power source potential and clamping a potential of the capacitive load to the power source potential such that an electric power is supplied to the capacitive load in a temporally dispersed manner. For example, the clamp circuit includes a plurality of switches parallelly connected between the capacitive load and the power source potential, the plurality of switches being turned on at different times.
