The present invention relates to a ferroelectric liquid crystal composition and a ferroelectric liquid crystal display element. The present invention provides a ferroelectric liquid crystal composition and a ferroelectric liquid crystal display element using this ferroelectric liquid crystal. The ferroelectric liquid crystal composition of the present invention contains at least one liquid crystal compound and has a chiral smectic C phase, and when the ferroelectric liquid crystal composition is sandwiched between substrates, a layer normal direction of the chiral smectic C phase is 80° to 90° with respect to the substrate surface. According to the ferroelectric liquid crystal composition and the ferroelectric liquid crystal display element of the present invention, since an alignment restoring ability is excellent, the present invention is useful for application in which a pressing force is repeatedly applied.
A ferroelectric liquid crystal composition which contains at least one type of liquid crystal compound and which has a chiral smectic C phase, wherein a layer normal direction of the chiral smectic C phase obtained when the ferroelectric liquid crystal composition is sandwiched between substrates is 80° to 90° with respect to the substrate surface.
