To improve the quality of a liquid crystal display device, writing of an image signal and lighting of a backlight are sequentially performed not in the whole pixel portion of the liquid crystal display device but in each given region of the pixel portion. Thus, the frequency of input of an image signal to each pixel of the liquid crystal display device can be increased. As a result, display degradation caused in the liquid crystal display device such as color break can be suppressed, and the quality of an image can be improved.
