Abstract:
A roll of multilayer optical film is described. The roll includes a substantially uniaxially-oriented multilayer optical film, where at least one layer of the multilayer optical film has indices of refraction in a length direction and a thickness direction that are substantially the same, but substantially different from an index of refraction in a width direction.
