  • Patterned retarder film and method for manufacturing the same
    Patent number: 8817209
    Abstract: Disclosed is a patterned retarder film which comprises a substrate, a patterned configuration layer and a liquid crystal layer. The patterned configuration layer includes a plurality of first regions and a plurality of second regions A liquid crystal layer is disposed on the patterned configuration layer, wherein liquid crystal molecules above the first regions is arranged irregularly because of the protrusions, the liquid crystal molecules above the second regions are aligned with the aligning micro-structures. The liquid crystal layer in above the first regions provides a first phase retardation, the liquid crystal layer above the second regions provides a second phase retardation, and the difference between the first phase retardation and the second phase retardation is 180°. The method for manufacturing the same is disclosed.
    Type: Grant
