Abstract: An exemplary roll of film includes an oriented optical film comprising a birefringent material characterized by an effective orientation axis and a normalized difference between a refractive index for light polarized along TD and a refractive index for light polarized along ND being less than 0.06. The optical film has a width of greater than 0.3 m and a length greater than 10 m, and the effective orientation axis is aligned along the length of the optical film (MD).
