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 film including a thermoplastic birefringent multilayer optical film and a UV-cured layer disposed adjacent an outer layer of the multilayer optical film is described. The outer layer has a thickness in a range of about 0.5 micrometers to about 1.0 micrometers and the UV-cured layer includes a structured surface opposite the outer layer. The UV-cured layer has a Tg less than about 30° C. and has a pencil hardness in a range of 2B to 2H.

Abstract: A backlight that includes an illumination device that has at least one light source, a circular-mode reflective polarizer, and a specular partial reflector is disclosed. The specular partial reflector is disposed between the illumination device and the circular-mode reflective polarizer. Furthermore, the specular partial reflector is in substantially direct polarization communication with the circular-mode reflective polarizer.
