An organic light-emitting diode (OLED) device, comprising: a substrate (10) ; an OLED (11) formed on .the substrate (10) comprising a first electrode (14) , one or more layers (16) of organic material, one of which emits light, and a transparent second electrode (18) , the transparent second electrode (18) and layer (s) of organic light-emitting material (16) having a first refractive index range; a transparent cover (12) having a second refractive index; separately formed spacer element particles (24) distributed above the transparent second electrode (18) , providing spacing between the transparent second electrode (18) and the cover (12) , and forming a transparent gap between the transparent second electrode (18) and the cover (20) , the transparent gap having a third refractive index lower than each of the first refractive index range and second refractive index; and separately formed light-scattering element particles (22) distributed over the second electrode (18) between the spacer element particles (24) . |
