Adjacent film layers each have different refractive indices. At least one of the film layers is discontinuous to form a form-birefringent layer with an array of parallel ribs having a period less than 400 nm. Another layer, different than the form-birefringent layer, is formed of an optically absorptive material for the ultra-violet spectrum.

Adjacent film layers have different refractive indices. At least one of the film layers is discontinuous to form a form birefringent layer with an array of parallel ribs with a period less than approximately 260 nm.
