    摘要: An optical film has a major surface including a plurality of microstructures. Each microstructure includes an optical facet and a sidewall meeting the optical facet at a ridge of the microstructure. The optical facet and the sidewall define an oblique angle therebetween. For each microstructure in at least a majority of the microstructures, an optically absorptive layer is disposed on the sidewall. The optical film can include a polymeric layer having a microstructured surface at least partially coated with an inorganic optically transparent layer. The optically absorptive layer can an average thickness t where 100 nm
