<P>PROBLEM TO BE SOLVED: To provide a liquid crystal display device for performing image display in accordance with ambient brightness, and provide a liquid crystal display device capable of image display in either a reflection mode with external light used as an illumination light source or a transmission mode with a backlight. <P>SOLUTION: A reflection region for performing display by reflection of light that enters via a liquid crystal layer and a transmission region for performing display by transmission of light from a backlight are provided, and switching between the reflection mode and the transmission mode is performed. For the display of full-color images, a pixel portion includes at least a first region and a second region, plural light rays with different hues are sequentially supplied to the first region according to a first rotation schedule and plural light rays with different hues are also sequentially supplied to the second region according to a second rotation schedule different from the first rotation schedule. In the transmission mode, the reflection region displays black to reflect external light in the reflection region, thereby preventing decrease in contrast. <P>COPYRIGHT: (C)2012,JPO&INPIT |
