摘要：
Liquid crystal polarizers are prepared by using a common linear polarizer, a nematic liquid crystal and PVA-coated glass substrates. The surface of one substrate is treated for unidirectional molecular orientation and the other substrate is treated for concentrically circular molecular orientation. The liquid crystal cell has axially symmetrical polarization properties, that is, a concentrically circular or radial polarization can be achieved.
