Title: Liquid crystal device and liquid crystal display apparatus having a chevron structure in monostable alignment

Abstract: A liquid crystal device has a pair of oppositely disposed substrates and a liquid crystal having chiral smectic C phase disposed therebetween. The liquid crystal is placed in an alignment state in chiral smectic C phase with smectic molecular layers forming a chevron structure. Under no electric field application, the liquid crystal has an average molecular axis substantially in alignment with the uniaxial alignment axis and/or a bisector of a maximum angle formed between two extreme molecular axes established under electric field application, while under electric field application, the liquid crystal provides an effective tilt angle and a transmittance that continuously changes depending on an electric field applied thereto.
