PROBLEM TO BE SOLVED: To provide a display device that is used on a compact mobile apparatus that achieves low power consumption, even when its displays are not switched for a long time, when a battery or the like is used as a power source, and is capable of reducing the number of components, even when a memory device is provided to a pixel, while maintaining a high aperture ratio. SOLUTION: The liquid crystal display device has a memory device in a pixel and achieves low power consumption by not transferring a video signal. Utilizing the voltage retained in the pixel memory of the liquid crystal display panel, the liquid crystal display device generates a signal for alternation drive inside the pixel, executes alternation drive, even when the video signal is not rewritten, and performs displaying without deteriorating liquid crystal. The liquid crystal display device realizes the memory device with a simplified configuration, and will not sacrifice the aperture ratio. COPYRIGHT: (C)2007,JPO&INPIT |
