A driver circuit includes a main driver which receives an input signal and outputs a first signal corresponding to the input signal, a sub driver which receives the input signal and outputs a non-inverted signal and an inverted signal corresponding to the input signal, a differentiating circuit including resistors and a variable capacity condenser, which outputs signals by differentiating the non-inverted signal and the inverted signal, respectively, and an addition unit which outputs a high frequency emphasized signal given by adding the output signal of the main driver and the signal given by differentiating the non-inverted signal, or a low frequency emphasized signal given by adding the output signal of the main driver and the signal given by differentiating the inverted signal. |
