ABSTRACT:
A liquid crystal device is constituted by a pair of substrates disposed in parallel and each provided with a transparent electrode, and a chiral smectic liquid crystal disposed between the pair of substrates. At least one of the substrates is provided with a uniaxial alignment control film which have been rubbed in at least two different directions. Liquid crystal molecules may preferably form a pretilt angle of at least 5 degrees with respect to the alignment control film.
