Abstract: An electrically conductive OLED carrier includes in this order a glazing substrate; an electrode arranged in a metal grid made up of strands; an electrically insulating light extraction layer under the metal grid; and a layer partially structured in its thickness. The layer of refractive is of index n3 of 1.7 to 2.3, and is located on the light extraction layer. The partially structured layer is formed from a region structured with cavities at least partially containing the metal grid; and from another region, called the low region, located on the light extraction layer. The separation H between the surface of the structured region called the high surface, and therefore that furthest from the substrate, and the surface of the metal grid called the upper surface, and therefore that furthest from the substrate is, in absolute value, smaller than or equal to 100 nm.
