Abstract: A nematic liquid crystal material which assumes a homeotropic texture is provided by dissolving an additive material having the formula RR3''N X wherein R is an alkyl radical having 10 to 24 carbon atoms, R'' is a methyl or ethyl radical, and X is an anion derived from a simple acid, in a nematic material. A typical example of the additive is hexadecyltrimethylammonium bromide. The homeotropic texture provided by this composition, when placed between two conducting transparent plates, is readily deformed by a voltage applied to the plates and can thereby be utilized to control the transmission of light.
