Abstract We have evaluated surface structures for out‐coupling film for applying to the top surface of OLED lighting devices to reduce the angular dependence of chromaticity. By the combination of optimized structure and scattering layer, improved optical properties were obtained while maintaining low rainbow colored surface reflections and scratch durability.
