Patterned retarder film and method for manufacturing the same

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°.
