To provide a display device in which reliability of a driver circuit can be improved by suppressing shift of the threshold voltage of a TFT. The minimum power supply voltage that is optimal for driving a transistor used in the driver circuit is found by actually changing voltage applied to a gate of the transistor. Specifically, voltage that is output from an output circuit included in the driver circuit when a value of power supply voltage applied to a shift register is changed is monitored. Then, a value of the power supply voltage is found such that a value of the voltage output from the output circuit satisfies a value enough to operate a pixel portion, and the driver circuit is operated using the power supply voltage.
