Abstract
An electro-optic material that is characterized by short reaction times when working with a low drive voltage. For that, the electro-optic material has a lamellar liquid crystal (,), which contains one or more components and into which chiral molecules (,), whose longitudinal axes (m) are longer than the longitudinal axes of the molecules (,) forming the lamellar liquid crystal, are introduced at a predefined concentration, so that the longitudinal axes (m) of the chiral molecules (,) are tilted, without an external electric field, statistically by a predefined angle (&thgr;,) toward the normal (z) of the layer of the lamellar liquid crystal (,).
