Patent ID: 8553187

Claim:
A method for manufacturing a patterned retarder film with a plurality of first retardation regions and a plurality of second retardation regions, comprising the steps of: providing a base film; forming an alignment layer on a first surface of the base film; coating a liquid crystal material on the alignment layer as a liquid crystal layer; aligning the liquid crystal layer with the alignment layer; embossing the liquid crystal layer with a predetermined pattern to form a patterned layer with a plurality of first retardation regions and a plurality of second retardation regions, wherein the structure of the first retardation regions and the second retardation regions are grating-like stripe structure and parallel to each other and the structure of the second retardation regions relative to that of the first retardation regions are grooving-like stripe structure and interleaved with each other; and curing the patterned liquid crystal layer; wherein the phase retardation of the first retardation region and that of the second retardation regions is different by 180°.
