ABSTRACT:
An optically active compound which itself generally exhibits no antiferroelectric liquid crystal phase, but which can be added to an antiferroelectric liquid crystal or composition thereof having a high threshold voltage to reduce the threshold voltage of the resulting composition. Also disclosed is an antiferroelectric liquid crystal composition containing the optically active compound, a process for reducing the threshold voltage of an antiferroelectric liquid crystal composition, a process for producing the optically active compound, and a process for producing an optically active carboxylic acid as an intermediate.
