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: To provide a semiconductor device including a narrowed bezel obtained by designing a gate driver circuit. A gate driver of a display device includes a shift register unit, a demultiplexer circuit, and n signal lines. By connecting the n signal lines for transmitting clock signals to one stage of the shift register unit, (n−3) output signals can be output. The larger n becomes, the smaller the rate of signal lines for transmitting clock signals which do not contribute to output becomes; accordingly, the area of the shift register unit part is small compared to a conventional structure in which one stage of a shift register unit outputs one output signal. Therefore, the gate driver circuit can have a narrow bezel.
