Abstract
A polarizer including liquid crystal material and a surface or surfaces for cooperating with the liquid crystal material to control polarization of light which is incident in a direction normal to the polarizer by at least one of refraction and total internal reflection of one polarization component of the light while transmitting the other polarization component substantially in the direction without refraction or total internal reflection, the surface or surfaces including plural grooves in cooperative relationship with the liquid crystal material.
