    摘要: A liquid crystal device is constituted by a chiral smectic liquid crystal and a pair of substrates sandwiching the chiral smectic liquid crystal therebetween and each having thereon an electrode for applying a voltage to the liquid crystal. At least one of the substrates being provided with an alignment control film comprising a specific aromatic polyimide which has been subjected to a uniaxial aligning treatment. The chiral smectic liquid crystal assumes bistability in a chiral smectic temperature range when incorporated in a test cell which is not provided with an alignment control film and has been subjected to shearing treatment. In the liquid crystal device including the polyimide alignment control film, the chiral smectic liquid crystal at least has a voltage-transmittance characteristic such that an effective tilt angle and a transmittance continuously change depending on an electric field applied thereto.
