Abstract
Nematic liquid crystal compositions including a relatively small amount of a charge-transfer acceptor dopant exhibit substantially different voltage-transmission characteristics in dynamic scattering as compared to undoped nematic liquids. Nematic compositions based on azoxy compounds and dopants of the cyano or halo tetra substituted quinone types are preferred.
