Abstract: Objects are to provide a display device the power consumption of which is reduced, to provide a self-luminous display device the power consumption of which is reduced and which is capable of long-term use in a dark place. A circuit is formed using a thin film transistor in which a highly-purified oxide semiconductor is used and a pixel can keep a certain state (a state in which a video signal has been written). As a result, even in the case of displaying a still image, stable operation is easily performed. In addition, an operation interval of a driver circuit can be extended, which results in a reduction in power consumption of a display device. Moreover, a light-storing material is used in a pixel portion of a self-luminous display device to store light, whereby the display device can be used in a dark place for a long time.

Abstract: A scan line to which a selection signal or a non-selection signal is input from its end, and a transistor in which a clock signal is input to a gate, the non-selection signal is input to a source, and a drain is connected to the scan line are provided. A signal input to the end of the scan line is switched from the selection signal to the non-selection signal at the same or substantially the same time as the transistor is turned on. The non-selection signal is input not only from one end but also from both ends of the scan line. This makes it possible to inhibit the potentials of portions in the scan line from being changed at different times.
