Compensation of the temperature dependence of the optical characteristics of twisted nematic liquid‐crystal displays using a single chiral dopant

Chiral dopants are reported which enable one to compensate for the temperature dependence of the optical characteristics of twisted nematic liquid‐crystal displays. Temperature compensation is achieved by the addition of a small amount of only one chiral compound to the liquid‐crystal mixture. This procedure is more precise and less laborious than a previously reported method, which utilizes two or more chiral dopants.
