Abstract
An optoelectronic device for light display includes a support; light elements electrically connected to at least one first electrode and including a light-emitting diode of which a doped part is arranged in situation of electrical contact with the first electrode, the first electrode covering at least one upper part of the doped part arranged on the side opposite to the support face. Light confinement walls are configured to have an ability to reflect all or part of the light emitted by at least one of the light elements and being arranged so as to surround all or part of the at least one light element. The light confinement walls are electrically conductive and directly connected to the first electrode.
