Abstract
A polarel panel includes a sheet polarizer in intimate juxtaposition with a layer made up of regions of isotropic material interspersed with regions of liquid crystal material. In one embodiment, optical activity of the liquid crystal material rotates the electric vector of incoming linearly polarized light through 90.degree. in selected areas. In another embodiment, birefringence causes rotation of the electric vector of incoming linearly polarized light through 90.degree. in selected areas.
