Abstract
A method for making a polarizer-and-compensator assembly includes: (a) forming an alignment film on a releasable substrate; (b) forming a liquid crystal film on the alignment film so as to form a compensator layer on the releasable substrate; and (c) transferring the compensator layer from the releasable substrate to a polarizer plate by removing the releasable substrate from the compensator layer and attaching the alignment film to the polarizer plate.
