Patent abstract
A process of creating a retarder using thin-stretched polymer film to perfectly conform to a curved mold and achieving nearly-crystallized lamination thanks to minimized thickness of said retarder using PVA film; thus, achieving greatly-enhanced optical clarity, contrast, and 3-D effect during stereoscopic image viewing and greatly-reduced user discomfort. A 3-D stereoscopic viewing lens having a retarder film using a PVA film filled with a gap filling agent to create a refringent effect, a polarized film and a base material.
