Abstract
A liquid crystal display device includes a pair of substrates, a plurality of pixels arranged in a matrix and a static memory formed on the substrates. A bit signal corresponding to an image data is written and held in a static memory in the pixel. The polarity of the input bit signal is controlled. A liquid crystal voltage supplied to a liquid crystal layer arranged between the pair of substrates is generated by the bit signal. The polarity of the bit signal is controlled to alternate the liquid crystal voltage, and a transmittance of the liquid crystal layer is changed by supplying the alternated liquid crystal voltage.
