Abstract
A liquid crystal composition having a high order, tilted ferro-electric achiral Smectic I phase exhibiting a relaxed cone angle of greater than 20.degree. in the absence of high surface tilt alignment layers at temperatures in the range of 5.degree. C. to 40.degree. C. and includes from 90% to 99.9% by weight of a mixture of at least two achiral host compounds and from 0.1% to 10% by weight of a chiral dopant compound.
