Abstract:
1. A patterned retarder film comprising: a substrate; a patterned configuration layer disposed on the substrate, comprising a plurality of first regions and a plurality of second regions, the first regions and the second regions being in a grating stripe structure and interlacedly parallel to each other, and the first regions relative to that of the second regions being in a relief structure, wherein the first regions have a top surface with a plurality of protrusions having a distance of 0.1 μm to 8 μm therebetween, and the second regions have a bottom surface with a plurality of aligning micro-structures; and a liquid crystal layer disposed on the patterned configuration layer, wherein liquid crystal molecules above the first regions are arranged irregularly because of the protrusions, and the liquid crystal molecules above the second regions are aligned with the aligning micro-structures; wherein the liquid crystal layer disposed above the first regions provides a first phase retardation, the liquid crystal layer above the second regions provides a second phase retardation, and the phase difference between the first phase retardation and the second phase retardation is 180°.
