    Abstract: A display device capable of improving the image quality is provided. The display device includes a pixel in which a first node, a second node, a third node, and a display element are provided, and the same image data is written to the first node and the second node first. Then, at the same time when the image data is read from the second node to the third node, the image data is added to the image data in the first node by capacitive coupling. This operation enables a data potential higher than or equal to the output voltage of a source driver to be supplied to the display element.

A pixel has a function of retaining first data, a function of adding second data to the first data to generate third data, and a function of supplying the third data to the display device. Capacitive coupling by a capacitor is used for data addition. Two pixels provided in the vertical direction (the direction in which a source line extends) share components including the capacitor; thus, the area where the two pixels are provided can be assigned to the capacitor, which can increase the capacitance value. Thus, the data addition by the capacitive coupling can be efficiently performed.
