Abstract
A main object of the present invention is to provide a liquid crystal display using a ferroelectric liquid crystal, showing the mono-stability operation mode using a material showing the chiral smectic C phase via the smectic A phase in the temperature lowering process as the ferroelectric liquid crystal. The present invention achieves the object by providing a reactive liquid crystal layer having a reactive liquid crystal fixed on at least one facing surface of the two alignment films in a liquid crystal display comprising two aligned substrates comprising a substrate, an electrode layer and an alignment film, disposed so as to have the alignment films face with each other, and a ferroelectric liquid crystal sandwiched between the aligned substrates.
