Patent Images
1. An arrangement for a polychrome display, comprising in serial association a light source, a linear polarizing filter, at least one electro-optical nematic liquid crystal rotating element adapted to rotate the plane of polarization of a light ray when no electrical potential is applied and to leave the plane of polarization unchanged when potential is applied, and a pleochroic color selective linear polarizer forming an assembly.
