Abstract

A method for manufacturing an optical compensator (5) on a transitional substrate (8) comprises applying a first orientation layer (20) to the transitional substrate. The first orientation layer (20) is then aligned and a first anisotropic liquid crystal material (30) is applied on the first orientation layer. In one embodiment, a retardation layer (10) is located between the transitional substrate (8) and the first orientation layer (20).
