ABSTRACT:
This invention is directed to reduce the viscosity of a naphthalene type mixed liquid crystal and to improve display quality while maintaining a bookshelf layer structure. The ferroelectric liquid crystal composition of the present invention comprises 70 to 97 parts by weight of a naphthalene base mixed liquid crystal and 3 to 30 parts by weight of a predetermined tolan type liquid crystal.
