In a display device which arranges a memory part for every display pixel, an erroneous operation of the memory part and the power consumption can be reduced. In a display device provided with a display panel which includes a plurality of display pixels, video lines which apply video data to the display pixels, and scanning lines which apply a scanning voltage to the display pixels, the display pixel includes a memory part which stores the video data, a pixel electrode, and a switching part which selectively applies a first video voltage or a second video voltage which differs from the first video voltage to the pixel electrode in response to the video data stored in the memory part.
