Claim:
1. A liquid crystal display device comprising: a plurality of pixels provided at intersection portions where a plurality of column data lines and a plurality of row scanning lines intersect with each other, wherein the pixel comprises: a display element configured to be filled and enclosed therein with liquid crystal between a pixel electrode and a common electrode opposing each other; a first switching unit configured to sample, through the column data line, each frame data of an input video signal for displaying the frame data using a plurality of sub-frames having a shorter display period than one frame period; a first holding unit configured a second switching unit configured to output the sub-frame data held by the first holding unit; and a second holding unit a pixel control unit configured a common voltage generation unit configured to invert at a start of each sub-frame a polarity of a common voltage to be applied to the common electrode opposing to the pixel electrode and also invert the polarity of the common voltage at a start of a predetermined processing period of frame rate control which includes a plurality of one frame periods to invert the sub-frame data held in the first holding unit in accordance with the polarity of the common voltage.
