Abstract (en)
[origin: WO2020083847A1] The present invention relates to an optoelectronic device (15) comprising a substrate (30) and at least two-sub-pixels (20), each sub-pixel (20) being suitable for emitting a first respective radiation, the substrate (30), each sub-pixel (20) comprising: - at least one fin (35) made of a first semiconductor material, the fin (35) along a normal direction perpendicular to the substrate, each fin (35) having first lateral side (75); - a covering layer (40) comprising one or more radiation-emitting layers (100), the covering layer (40) extending over the first lateral side (75) of each fin (35), the sub-pixels (20) defining a void that is located between the two sub-pixels (20), and a blocking structure (25) being inserted into the void between the two sub-pixels (20), the blocking structure (25) being suitable for preventing the first radiation emitted by one sub-pixel (20) from reaching the other sub-pixel (20) through the blocking structure.
