    • This invention offers a power supply circuit that is capable of improving a power factor as well as reducing a ripple current of an input/output of the power supply circuit due to switching of a switching device. The power supply circuit is provided with a first power supply circuit including first and second switching devices, a second power supply circuit including third and fourth switching devices and a switching control circuit. The switching control circuit controls the switching devices so that the first switching device and the third switching device are turned on and off at timings different from each other when an alternating current voltage from an alternating current power supply is positive, and the second switching device and the fourth switching device are turned on and off at timings different from each other when the alternating current voltage is negative.

    • A liquid crystal display driver includes a first selecting circuit configured to select a voltage from a first voltage range based on a digital signal; and a second selecting circuit configured to select a voltage from a second voltage range based on the digital signal. A voltage which is applied between a diffusion layer and a back gate of a first MOS transistor contained in the first selecting circuit is smaller than a voltage which is applied between a diffusion layer and a back gate of a second MOS transistor contained in the second selecting circuit. Also, an offset length of the first MOS transistor is shorter than that of the second MOS transistor. The liquid crystal display driver may further include a voltage generating circuit configured to supply gradation voltages of the first voltage range and the second voltage range to the first and second selecting circuits. One of the first and second selecting circuits outputs one of the gradation voltages based on the digital signal.
