In a source driver for a liquid crystal display device, a slew rate is increased while an increase in power consumption is suppressed. The source driver for a liquid crystal display device includes multiple output amplifiers that drive multiple data lines in response to an input signal, and a bias control circuit having a dummy amplifier consistent with an electric characteristic of the output amplifiers. The bias control circuit controls high bias periods of the output amplifiers on the basis of an output transition period of the dummy amplifier when the dummy amplifier receives voltages of a γ resistor circuit, which are input to the output amplifiers. |
