An object is to reduce residual images and power consumption in a liquid crystal display device. The liquid crystal display device capable of inputting an image signal to a pixel portion selectively is provided. It is possible for the liquid crystal display device to input the image signal only to a region in which a fast-moving image is displayed. Therefore, residual images in displaying a moving image can be reduced. Further, in the liquid crystal display device, it is acceptable that the image signal is not input to a region in which a slow-moving image is displayed; accordingly, power consumption can be reduced. |
