Abstract

A curved reflective has at least one location having a radius of curvature in a range from about 6 mm to about 1000 mm. Each location on the reflective polarizer has a maximum reflectance greater than about 70% for a block polarization state, a maximum transmittance greater than about 70% for an orthogonal pass polarization state, and a minimum transmittance for the block polarization state. For a continuous first portion of the reflective polarizer extending between different first and second edges of the reflective polarizer and defining disjoint second and third portions of the reflective polarizer, the minimum transmittance of the reflective polarizer for the block polarization state is higher at each location in at least 70% of the first portion than at each location in at least 70% of the second portion and at each location in at least 70% of the third portion.
