ABSTRACT:
A nematic liquid crystal cell operating in a field effect scattering mode employs a surfactant to provide homogeneous random alignment of the nematic director. Field effect scattering mode operation improves over dynamic scattering mode operation by using an electric field to switch between homeotropic and homogeneous random alignment.
