    • An object of the invention is to suppress degradation in image quality of a liquid crystal display device which performs display by field sequential method and to reduce power consumption of a backlight. The highest brightness of a first color light in a pixel region is detected. Gamma correction is performed so that transmittance of a pixel of the region displaying the highest brightness of the first color light is set to maximum and transmittance of other pixel of the region is decreased in accordance with lowering of the first color light intensity, and the region is irradiated with the highest brightness of the first color light. Similarly, a second color light is irradiated in another region concurrently with irradiation of the first color, whereby input of an image signal and lighting of the backlight are performed simultaneously in every region of the pixel portion.

    • An object is to provide a liquid crystal display device capable of image display according to an environment around the liquid crystal display device, e.g., in a bright environment or a dim environment. Another object is to provide a liquid crystal display device capable of displaying an image in both modes of a reflective mode in which external light is used as a light source and a transmissive mode in which a backlight is used. In order to achieve at least one of the above objects, a liquid crystal display device is provided with a region (a reflective region) where display is performed with reflection of incident light through a liquid crystal layer and a region (a transmissive region) where display is performed with transmission of light from a backlight and can switch the transmissive mode and the reflective mode. In the case where a full-color image is displayed, a pixel portion includes at least a first region and a second region, a plurality of lights of different hues are sequentially supplied to the first region according to a first order, and a plurality of lights of different hues are also sequentially supplied to the second region according to a second order which is different from the first order.
