A driver circuit for outputting an output signal corresponding to an input signal given to the driver circuit, includes a voltage generating unit for outputting a basic output voltage corresponding to the input signal, a first buffer circuit for outputting an output voltage corresponding to the basic output voltage outputted by the voltage generating unit, a second buffer circuit, of which power consumption is larger than the first buffer circuit, for generating and outputting a voltage corresponding to the output voltage as the output signal, a simulating circuit including a simulating buffer circuit for generating a simulated voltage corresponding to the basic output voltage outputted by the voltage generating unit, the simulating buffer circuit having substantially the same characteristic as that of the first buffer circuit, and a controlling unit for controlling the basic output voltage outputted by the voltage generating unit based on the simulated voltage.
