<p>A ferroelectric liquid crystal composition having a chiral smectic C-phase is disposed as a liquid crystal composition layer between a first substrate and a second substrate arranged between two polarizing plates of which the planes of polarization are orthogonal to each other. The substrates are provided with vertically oriented films, respectively, and at least one of them is provided with orientation treatment that can form a pretilt angle in a certain direction. The C-director of the liquid crystal molecule is oriented in the certain direction at a portion being in contact with the substrate provided with the orientation treatment and is twisted by at least 180° between the first substrate and the second substrate. At least one of the substrates is provided with a pair of electrode structures generating electric fields approximately parallel to each other.</p> |
