A liquid crystal compound having (a) deuterium atom (s) and a liquid crystal composition comprising the said compound

摘要

Object It is possible to control a pitch without any increase of a viscosity and any decrease of a voltage holding ratio etc. in various liquid crystal compositions. Structure Provision of a liquid crystal compound with (an) optically active carbon atom(s) bonded to (a) deuterium atom(s) and a liquid crystal compound having characteristics suitable for various liquid crystal display methods at the same time. Effect It is possible to prepare a liquid crystal composition without use of a chiral dopant. It is possible to control a pitch length and a spiral direction by selection of a stereochemistry in the compound and (a) position(s) of the deuterium atom(s).
