An organic light-emitting diode (OLED) device including a substrate; an OLED formed on the substrate; a transparent cover provided over the OLED through which light from the OLED is emitted; separately formed spacer element particles having a first average size distributed above the OLED, providing spacing between the OLED and the cover, and forming a transparent gap between the OLED and the cover, and separately formed light-scattering element particles distributed over the OLED between the spacer element particles, having a second average size smaller than the first size and for scattering light emitted by the OLED.
