Abstract: Rolls of film are described. In particular, rolls of film including multilayer birefringent polarizers having low pass axis variation are described. The multilayer birefringent polarizers have low pass axis variation across a full crossweb width of the roll of film.

Abstract: Optical bodies are described. In particular, optical bodies having a birefringent multilayer optical film and a continuous adhesive layer with a thickness less than 20 micrometers are described. Optical bodies described herein exhibit reduced occurrence and severity of a non-uniformity defect known as “orange peel.”

Abstract: An optical film includes a plurality of alternating first and second polymeric layers, such that the first polymeric layers have a smaller average in-plane index of refraction than the second polymeric layers and the first polymeric layers have a glass transition temperature of at least 107 deg. C. The optical film may be a reflective polarizer. An optical stack includes a linear absorbing polarizer and the reflective polarizer disposed on, and bonded to, the absorbing polarizer. The reflective polarizer has an optical reflectance of at least 60% for a first polarization state and an optical transmittance of at least 60% for an orthogonal second polarization state. When heated at 105 deg. C. for 15 minutes, a difference in shrinkage of the reflective polarizer and the absorbing polarizer along the first and second polarization states is greater than about zero and 0.2%, respectively.

Abstract: Multilayer reflective polarizers are described. More particularly, multilayer reflective polarizers having a higher block light transmission at longer wavelengths than shorter wavelengths while having a high pass light transmission are described. The described multilayer reflective polarizers may be combined with absorbing polarizers or used in display devices.

Abstract: Thermoplastic birefringent multilayer optical films are described. More particularly, thermoplastic multilayer films having alternating first and second layers having a linear layer profile where both outer layers are thinner than 350 nm but thicker than 150 nm are described. Thermoplastic birefringent multilayer optical films with thinner outer protective boundary layers are described.

Abstract: An optical stack includes a liquid crystal panel with a color filter array. The liquid crystal panel has a filter side closest to the color filter array and a non-filter side opposite the filter side. An absorbing polarizer is laminated directly to the filter side of the liquid crystal panel, and a reflective polarizer laminated directly to the absorbing polarizer.

Abstract: Optical stacks including a first reflective polarizer and a partially reflective component are described. The partially reflective component may be a second reflective polarizer or a collimating reflector. The first reflective polarizer has a first average visible light reflectance for light polarized along the first block axis at normal incidence of at least 90 percent and a first average visible light transmittance for light polarized along the first pass axis at normal incidence of at least 85 percent. The second reflective polarizer has a second block axis and a second average visible light reflectance for light polarized along the second block axis at normal incidence being no more than the first average visible light reflectance minus 10 percent. The first and second block axes are not parallel and the first and second reflective polarizers have different f-ratios.

Abstract: Optical stacks are described. In particular, optical stacks including reflecting-absorbing polarizers and quarter-wave plates are disclosed. The optical core of the optical stack—which includes a reflecting-absorbing polarizer with at least one skin layer including polarizing dye—may be co-extruded or co-stretched.
