Abstract
An optoelectronic device including a semiconductor substrate that is optionally doped with a first type of conductivity; a first semiconductor region that is electrically connected to the substrate, doped with the first type of conductivity or a second opposite type of conductivity and more strongly doped than the substrate; a first set of first light-emitting diodes resting on the first semiconductor region, the first light-emitting diodes comprising wire-like, conical or frustoconical semiconductor elements; and a conductive portion in contact with the first semiconductor region.
