Abstract:
1. A liquid crystal display device comprising a first substrate, a second substrate, a liquid crystal composition sandwiched between said first substrate and said second substrate, a plurality of pixels disposed on said first substrate, each of said plurality of pixels being supplied with a video signal via a switching element connected to a first electrode thereof, each of said plurality of pixels being provided with a capacitance, one of two capacitance-forming electrodes forming said capacitance being connected to said first electrode of a corresponding one of said plurality of pixels, and another of said two capacitance-forming electrodes being supplied with a pixel-potential control signal, wherein a polarity of said video signal reverses with respect to a first reference voltage with a repetition period, and wherein said pixel-potential control signal alternates between two voltage levels of the same polarity with respect to a second reference voltage such that a voltage on said first electrode of the corresponding one of said plurality of pixels changes into a reserve polarity with respect to the first reference voltage.
