Abstract
An electro-optical device including a biaxial liquid crystal having a primary and secondary director is provided. A change in orientation of at least one of the directors due to an applied electric field produces a change in the optical state of the device. Response times are increased dramatically over uniaxial nematic based liquid crystal devices, offering improved performance and efficiency.
