Abstract: A display device in which high voltage can be applied to a display element is provided. A display element includes a pixel provided with a display element including a pixel electrode and a common electrode, and the pixel is electrically connected to a first data line and a second data line. Supply of a first potential to the pixel through the first data line and supply of a second potential to the pixel through the second data line are performed concurrently, and then a third potential is supplied to the pixel through the second data line, whereby the first potential held in the pixel is changed to a fourth potential, and the fourth potential is applied to the pixel electrode. Here, the second potential is a potential calculated based on the first potential. When the value of the second potential is less than or equal to a potential applied to the common electrode, the third potential is higher than the potential applied to the common electrode. In contrast, when the value of the second potential is greater than or equal to the potential applied to the common electrode, the third potential is lower than the potential applied to the common electrode.

Abstract: A semiconductor device includes a display device and a source driver. Each of a plurality of pixels included in the display device is supplied with a first data potential and a second data potential included in a range of a first potential or higher to a second potential or lower. The first data potential makes the pixel display an image with a first gray level. The pixel performs calculation with the first data potential and the second data potential to generate a third data potential. The third data makes the pixel display an image with a second gray level. A reference potential of the first data potential is an intermediate potential between the first potential and the second potential, and the gray level width that can be displayed by the second data potential is larger than the gray level width that can be displayed by the first data potential.
