Electrooptic Effects in Liquid Crystal Materials [Paperback]

Electrooptic effects provide the basis for much liquid-crystal display technology. This book, by two of the leaders in liquid-crystal research in Russia, presents a complete and accessible treatment of virtually all known phenomena occurring in liquid crystals under the influence of electric fields.Electrooptic effects provide the basis for much liquid-crystal display technology.
