A liquid-crystalline polymer composition comprising a ferroelectric liquid-crystalline polymer and a low molecular weight liquid-crystalline compound which exhibits smectic C phase or chiral smectic C phase. Such liquid-crystalline polymer compositions have not only excellent moldabilities such as ease of orientation, but also exhibit chiral smectic C phase at wide temperature range within room temperatures and exhibit high speed response to changes of external fields and high contrast ratios when they are used for optical display elements.
A liquid crystal polymer which contains a polymer having a proton donor and/or proton acceptor and showing no liquid crystal properties and a low-molecular compound having within its molecule a proton acceptor and/or a proton donor capable of forming a hydrogen bond with the proton donor and/or proton acceptor of the polymer. This polymer can form a smectic phase at lower temperatures and is useful in the field of optoelectronics.
