Abstract: An emissive article includes an OLED having a light emission surface, a circular polarizer, and a light extraction film optically between the OLED and the circular polarizer and being optically coupled to the light emission surface. The light extraction film includes a two-dimensional structured layer of extraction elements having a first index of refraction and a pitch in a range from 400 to 800 nm and a backfill layer including a material having a second index of refraction different from the first index of refraction.
