Abstract
A display device which arranges a memory part for every display pixel is configured to prevent a charge from remaining in liquid crystal when a power source is turned off. Each display pixel includes a memory part for storing video data, a pixel electrode, and a switch part for selectively applying a first video voltage or a second video voltage different from the first video voltage to the pixel electrode corresponding to the video data stored in the memory part. The display device further includes a reset circuit for allowing the first video voltage and the second video voltage to have the same voltage when a power source of the display device is turned off.
