摘要： Multilayer optical film reflective polarizers previously considered to have excessive off-axis color can provide adequate performance in an LC display in an “on-glass” configuration, laminated to a back absorbing polarizer of the display, without any light diffusing layer or air gap in such laminate. The reflective polarizer is a tentered-one-packet (TOP) multilayer film, having only one packet of microlayers, and oriented using a standard tenter such that birefringent microlayers in the film are biaxially birefringent. The thickness profile of optical repeat units (ORUs) in the microlayer packet is tailored to avoid excessive perceived color at normal and oblique angles. Color at high oblique angles in the white state of the display is reduced by positioning thicker ORUs closer to the absorbing polarizer, and by ensuring that, with regard to a boxcar average of the ORU thickness profile, the average slope from an ORU(600) to an ORU(645) does not exceed 1.8 times the average slope from an ORU(450) to the ORU(600).

摘要： Multilayer optical film reflective polarizers previously considered to have excessive off-axis color can provide adequate performance in an LC display without any high haze light diffusing layer or air gap between the reflective polarizer and the back absorbing polarizer of the display. The reflective polarizer has only one packet of microlayers, and is oriented using a standard tenter such that birefringent microlayers in the film are biaxially birefringent. The microlayers in the packet have a layer thickness profile suitably tailored to avoid excessive perceived color at normal and oblique angles. A laminate made by combining this type of reflective polarizer with an absorbing polarizer, without an air gap or any high haze light diffusing layer or structure between the polarizers, can be used and incorporated into a liquid crystal display or the like with adequate color performance both at normal incidence and oblique incidence up to a polar angle of 60 degrees.

摘要： Multi-layer optical films that can be utilized as polarizer or mirror films and can be incorporated into optical stacks. The optical film includes a plurality of alternating polymeric first and second interference layers numbering greater than 50 and disposed between, and integrally formed with, first and second skin layers, each of the first and second interference layers has an average thickness less than 250 nm. The first and second interference layers and the first and second skin layers are compositions that include polyester.

摘要： A polarizer stack including an absorbing polarizer and a multilayer polymeric reflective polarizer bonded together is described. The absorbing polarizer has a first block axis and the reflective polarizer has a second block axis substantially parallel to the first block axis. The reflective polarizer may be substantially free of micro-wrinkling when the polarizer stack adhered to a glass layer is heated at 95° C. for 100 hours.

The at least one rough strippable skin layer can include a continuous phase and a disperse phase. In some embodiments, the at least one rough strippable skin layer can include a first polymer, a second polymer different from the first polymer and an additional material that is substantially immiscible in at least one of the first and second polymers.
