ABSTRACT:
A liquid crystal device comprising a pair of parallel base plates and a ferroelectric liquid crystal disposed between the base plates. One of the pair of parallel base plates is provided with a plurality of stepwise elevations disposed in the form of stripes, and has been implemented with a uniaxial orientation treatment in a direction parallel to the edges of the stepwise elevations. The stepwise elevation may be formed by a transparent electrode alone or in combination with an alignment control film disposed thereon. Because of the above features, alignment defects liable to develop from the edges of the elevations are removed.
