PROBLEM TO BE SOLVED: To provide a driving method for reducing the power consumption of a display device.SOLUTION: In the driving method, in a still image display mode, by starting the output of a driving signal and a power supply voltage to a first driver circuit and starting the output of the driving signal and the power supply voltage to a second driver circuit, an image signal is output to n pieces of pixels. After that, the operation of stopping at least the output of the driving signal and the power supply voltage to the second driver circuit and holding an image of a pixel portion, based on the input image signal as a still image is performed N (N is a natural number) times. When N is 2 or more, the length of the period of stopping the output of the driving signal and the power supply voltage to the second driver circuit in a K-th (K is a natural number ≥2 and ≤N) time is set longer than the period of stopping the output of the driving signal and the power supply voltage to the second driver circuit in a (K-1)-st time. |
