    • A liquid crystal display device includes upper and lower substrates having upper and lower electrodes formed on a surface of respective upper and lower substrates, and upper and lower orientation films formed over the surface of respective upper and lower electrodes. A nematic liquid crystal is sandwiched between the upper and lower substrates. A driver mechanism shifts the longitudinal axes of molecules of the liquid crystal, and is adapted to apply a voltage to the liquid crystal for selectively and bistably executing switching between a first state in which the longitudinal axes of liquid crystal molecules adjacent the upper substrate have a tilt angle with respect to the upper substrate and the longitudinal axes of liquid crystal molecules adjacent the lower substrate are parallel to the lower substrate, while the longitudinal axes of liquid crystal molecules adjacent the upper and lower substrates projected on the planes of the upper and lower substrates are oriented in a generally same direction, and a second state wherein the longitudinal axes of the liquid crystal molecules adjacent the lower substrate have a tilt angle with respect to the cross-sectional direction of the lower substrate and the longitudinal axes of the liquid crystal molecules adjacent the upper substrate are parallel to the cross-sectional direction of the upper substrate, while the longitudinal axes of the liquid crystal molecules adjacent the lower and upper substrates projected on the lower and upper substrates are oriented in a generally same direction.
