Abstract:
A main object of the present invention is to provide a birefringence improving agent that can realize a satisfactory white display even in a liquid crystal display device in which a ferroelectric liquid crystal composition is used and which can reduce the birefringence and has a large cell gap; a ferroelectric liquid crystal composition and a liquid crystal display device that use the birefringence improving agent; and a compound that can be used in a ferroelectric liquid crystal composition.
