ABSTRACT:
A method of forming a reflective polarizer comprising orienting a multilayer film formed from alternating layers of a first polymeric material and a second polymeric material in a first in-plane axis direction while allowing dimensional relaxation in an orthogonal second in-plane axis direction to produce specified differences in the refractive indices of the first and second polymeric materials in the first and second in-plane directions and in the thickness direction.
