A method for reducing power consumption of a source driver included in a display device and suppressing heat generation is provided. In a display device in which each pixel is supplied with a data signal of image data through a source line, a source driver is included, each source line is electrically connected to the source driver, and the source driver has a function of driving the source lines.In the case where the amount of change of the data signal of the image data is small, in other words, in the case where power for charging and discharging the source line can be small, the source driver reduces the apparent size of the transistor at the output stage, and power consumption can be reduced. Furthermore, the amount of heat generation can be reduced. 提供一种降低包括在显示装置中的源极驱动器的功耗并抑制发热的方法。在通过源极线对每个像素供应图像数据的数据信号的显示装置中，包括源极驱动器，每个源极线电连接到源极驱动器，并且源极驱动器具有驱动源极线的功能。在图像数据的数据信号的变化量小的情况下，换言之，在可以以小电力对源极线进行充放电的情况下，源极驱动器减小输出级的晶体管的外观上的尺寸，而可以降低功耗。此外，可以减少发热量。
