Abstract
A liquid crystal display device which includes a first substrate, a second substrate, a liquid crystal composition sandwiched between the first substrate and the second substrate, and a plurality of pixels disposed on the first substrate. Each of the plurality of pixels is supplied with a video signal via a switching element. Each of the plurality of pixels is provided with a capacitance having two electrodes in which one is connected to a first electrode of a corresponding one of the plurality of pixels and another is supplied with a pixel-potential control signal by a pixel-potential control circuit. The pixel-potential control circuit enables selection of a first voltage level and a second voltage level.
