Abstract
The manufacture of an optoelectronic device includes the formation of wire-like shaped light-emitting diodes and the formation of spacing walls transparent to the light radiation originating from the diodes. The lateral sidewalls of each diode are surrounded by at least one of the spacing walls. Light confinement walls directly cover the lateral sidewalls of the spacing walls by being in contact with the latter. The radiation originating from each diode and directed in the direction of the adjacent diodes is blocked by the confinement wall. The upper borders of the diodes are covered by the light confinement material so as to ensure a light extraction by the rear face of the optoelectronic device. An optoelectronic device is also described as such.
