Patent ID: 8867001

Claim:
A patterned retardation film, comprising: a base substrate; a patterned resin layer disposed on the base substrate, wherein the patterned resin layer has a plurality of first areas and a plurality of second areas, the combination of the first areas and the second areas are a grating-like stripe structure, the first areas are a relief-like stripe structure, the first areas are substantially interlaced and parallel to the second areas, and the patterned resin layer comprises: an aligning micron structure disposed on a surface of the patterned resin layer, wherein the aligning micron structure comprises: a plurality of first sub micron grooves formed on a top surface of each first area, wherein the first sub micron grooves are substantially parallel to a first extension direction of the first areas; and a plurality of second sub micron grooves formed on a bottom surface of each second area, wherein the second sub micron grooves are substantially parallel to a second extension direction of the second areas; and a liquid crystal layer disposed on the patterned resin layer and aligned with the aligning micron structure.
