An organic light-emitting diode (OLED) device, comprising: a first electrode and a second electrode having one or more organic layers formed there-between, at least one organic layer being light-emitting, the first and second electrodes defining one or more light-emissive areas, at least one of the electrodes being transparent; a transparent insulator layer formed adjacent to the transparent electrode opposite the one or more organic layer(s); and one or more reflective, electrically-conductive bus formed in a layer adjacent to the transparent insulator layer opposite the transparent electrode, wherein the reflective, electrically-conductive bus comprises a reflective surface directed towards the light-emitting layer and covers only a portion of the light-emissive areas.
