Abstract: Display data of pixels is updated at different timings. A scan line is connected to a first pixel and a second pixel, a first wiring is connected to the first pixel, and a second wiring is connected to the second pixel. In a first period, a signal for selecting the first pixel and the second pixel is supplied to the scan line. Setting data for setting a state where the display data of the first pixel is updated is supplied to the first wiring, and setting data for setting a state where the display data of the second pixel is updated is supplied to the second wiring. In a second period, a signal for selecting the first pixel and the second pixel is supplied to the scan line. Setting data for setting a state where the display data of the first pixel is not updated is supplied to the first wiring, and the setting data for setting the state where the display data of the second pixel is updated is supplied to the second wiring. In a third period, the first pixel displays first display data, and the second pixel displays second display data.
