ELECTRO-OPTIC LIQUID CRYSTAL SYSTEM WITH POLYAMIDE RESIN ADDITIVE

摘要

An electro-optic system wherein a layer of nematic liquid crystalline composition which is optically uniaxial with the optic axis normal to the plane of the layer has an electrical field applied perpendicular to the optic axis of the composition layer thereby inducing optical biaxiality in the composition layer. Electro-optic cells and imaging systems are disclosed using the optic retardation accompanying a field induced change from the uniaxial to the biaxial state.
