PATTERNED RETARDER FILM

摘要

Disclosed herein is a patterned retarder film for 3D display. The patterned retarder film includes a substrate, a patterned retarder layer and a micro-louver structure. The patterned retarder layer on the surface of the substrate has a plurality of first retardation micro structures and a plurality of second retardation micro structures and can split the image into two phase of images to form stereo image; the micro-louver structure is disposed between the substrate and the patterned retarder layer at the boundary of the first retardation micro structures and the second retardation micro structures. The micro-louver structure can decrease the crosstalk of the 3D display at vertical viewing angle and does not decrease the brightness of the 3D display at normal viewing angle.

1. A patterned retarder film for 3D display comprising:
a substrate; a patterned retarder layer on the substrate having a plurality of first retardation micro structures and a plurality of second retardation micro structures, wherein the plurality of first retardation micro structures and the plurality of second retardation micro structures are stripe structures, and the stripe structures are parallel to and interleaved with each other; and a micro-louver structure disposed between the substrate and the patterned retarder layer at the boundary area of the first retardation micro structures and the second retardation micro structures, wherein the micro-louver structure is extending in the direction of the first retardation micro structures and the second retardation micro structures.
