    Abstract: Provided are additive liquid crystalline compounds that, when added to one or more other components, form a mixture which can be supercooled. One class of additive liquid crystalline compounds are silyl-containing liquid crystalline compounds. Also provided are devices incorporating one or more silyl-containing liquid crystalline compound described herein and optionally one or more other components. The invention also includes the method of using liquid crystalline mixtures containing silyl-containing liquid crystalline compounds to suppress the crystallization, in a liquid crystal cell, of these mixtures at temperatures below their crystallization point.
