Abstract
A patterned retarder film with a plurality of first retardation regions and a plurality of second retardation regions and a method for manufacturing the same are provided. The method includes 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 and second retardation regions. The structure of the first and second retardation regions are grating-like stripe structure and parallel to each other and the structure of the second retardation regions are grooving-like stripe structure and interleaved with each other. The patterned liquid crystal layer is cured. The phase retardation of the first and second retardation regions is different by 180°.
