| 20160377775 | PATTERNED PHASE DIFFERENCE FILM AND METHOD FOR MANUFACTURING SAME - A pattern phase difference film is manufactured by a process including a laminate body formation step of applying a pattern alignment layer composition on a substrate to form a laminate body, a heat-drying layer formation step of heat-drying the composition to form a heat-dried layer, a pattern alignment layer formation step of irradiating a polarization pattern onto the heat-dried layer to form a pattern alignment layer, and a phase difference layer formation step of forming a phase difference layer including a rod-shaped compound on the pattern alignment layer. During the steps between the heat-drying layer formation step and the phase difference layer formation step, the heat-dried layer and the pattern alignment layer are exposed to the air for four hours or less. | 12-29-2016 |
| 20160377781 | OPTICAL FILM STACK INCLUDING RETARDATION LAYER - Optical film stacks are described. More particularly, optical film stacks including a half-wave retardation layer are described. Achromatic half-wave retardation layers, including achromatic half-wave layers formed from a quarter-wave and a three-quarters-wave retardation layer, are described. Film stacks including reflective polarizers tuned to reduce wavelength dispersion of the half-wave retardation layer are also described. | 12-29-2016 |
