Abstract
An optoelectronic device including a substrate including first and second opposite surfaces and lateral electrical insulation elements extending in the substrate and delimiting first electrically-insulated semiconductor or conductive portions. The optoelectronic device includes, for each first portion, an assembly of light-emitting diodes electrically coupled to the first portion. The optoelectronic device includes an electrode layer covering all the light-emitting diodes, a protection layer covering the electrode layer, and walls extending in the protection layer and delimiting second portions surrounding or opposite the assemblies of light-emitting diodes. The walls contain at least one material from the group including air, a metal, a semiconductor material, a metal alloy, a partially transparent material, and a core made of an at least partially transparent material covered with an opaque or reflective layer.
