Abstract
A light Emitting Diode includes a lower layer, an upper layer and between them an emissive structure suitable to emit a light radiation when an electric current passes through it. The upper layer is delimited by an upper surface, through which a portion at least of the light radiation exits. The lower layer is delimited by a lower surface for injecting electric charges. The upper surface forms a non-planar three-dimensional structure with hollow patterns and is covered by a contact structure made of one or several electrically-conductive materials, which extends against the surface, conforming to this non-planar surface.
