Classification: CPC H  B | IPC B  H

Claim 8:
9. An optoelectronic device, comprising:
an array of light-emitting diodes where each light-emitting diode of the array of light-emitting diodes has an elongate wire-like shape according to a longitudinal axis extending according to a transverse direction of the optoelectronic device,
spacing walls made of a first dielectric material transparent to the light radiation originating from the light-emitting diodes, the spacing walls being arranged such that lateral sidewalls of each light-emitting diode of the array of light-emitting diodes, over an entire height thereof considered according to the transverse direction, are surrounded by at least one of the spacing walls,
and light confinement walls made of a second material adapted to block light radiation originating from the light-emitting diodes, the light confinement walls directly covering lateral sidewalls of the spacing walls by being in contact with the spacing walls, the light radiation originating from each light-emitting diode of the array of light-emitting diodes and directed in the direction of an adjacent light-emitting diode of the array of light-emitting diodes being blocked by the light confinement walls which covers the spacing walls that surround the light-emitting diodes,
wherein the light confinement walls are formed by a thin layer of the second material obtained through a deposition implemented so that the thin layer of the second material directly covers the lateral sidewalls of the spacing walls by being in contact with the spacing walls and covers upper borders of the light-emitting diodes and wherein empty spaces delimited between the spacing walls at a level of areas between the light-emitting diodes are filled by the thin layer of the second material.
