An electrically conductive OLED carrier includes a glazing substrate; an electrode arranged in a metal grid made up of strands; an insulating light extraction layer under the metal grid; and a layer partially structured in its thickness, this layer being of given composition and of refractive index n3 of 1.7 to 2.3, and being located on the light extraction layer, which partially structured layer is formed from a region structured with cavities containing the metal grid, and from another region, called the low region, located on the light extraction layer, the separation H between that surface of the structured region called the high surface, and that surface of the metal grid called the upper surface, and therefore that furthest from the substrate, is larger than 100 nm. The strands have along their length a central zone between lateral zones that are flush with the high surface.
