ABSTRACT:
A polarization separator including a nematic liquid crystal (3) trapped between two transparent slides (1 and 2). The slide faces in contact with the liquid crystal are treated so that the liquid crystal molecules in contact with the faces are, for one of the faces (1) parallel to the face and, for the other face (2) perpendicular to the face. An incident light beam containing P polarization and S polarization is received at an oblique angle, and the directrix rotates the S polarization state as the light propagates through the device. The element is employed in a display system as a polarized light source.
