We investigated how to achieve desired optical properties of quarter wave retardation films QWFs that increase the viewing angle of time‐sequential stereoscopic 3D liquid crystal displays LCDs, such as high luminance, low crosstalk, low color change, and low head‐tilt‐angle dependency. These display properties were strongly affected by the out‐of plane retardation Rth of the QWF. We developed QWFs whose in‐plane and out‐of‐plane retardation are independently controllable by adjustment of a polymerized discotic material layer and a triacetate cellulose film, and 3D‐LCDs with high viewing angle properties were realized using these QWFs whose Rth was nearly zero.
