Abstract: The image quality of a liquid crystal display device that can display stereoscopic images is improved without the decrease in resolution. In a method for driving a liquid crystal display device that displays stereoscopic images by a wavelength division method, a first image seen with left eye and a second image seen with right eye are displayed using R, G, and B whose wavelength bands are different from each other by a field-sequential method. In the field-sequential method, writing of video signals and lighting of a backlight are sequentially performed not in the entire pixel portion but in each given region of the pixel portion.

Abstract: To provide a display device in which rewriting of only a given section of an image can be achieved or to simplify the configuration of a circuit including wirings in a display device in which partial driving can be performed. A shift of a selection signal in a shift register included in a scan line driver circuit and supply of a selection signal to scan lines are controlled independently of each other, so that rewriting of only a given section of an image can be achieved. The above operation is realized by providing a wiring that supplies a signal representing a clock signal or a fixed potential. Therefore, the configuration of the circuit including the wiring can be simplified in the display device including the wiring while partial driving can be performed.
