A display device capable of improving image quality with low power consumption is provided. A storage node is provided in each pixel and a first signal can be held in the storage node. A second signal is added to the first signal by capacitive coupling to generate a third signal. A display element operates in response to the third signal. Thus, regardless of the output voltage of a driver that supplies data, a high voltage can be supplied to the display element. Consequently, even a display element that requires a relatively high voltage for operation can operate with low power consumption.
