OPTOELECTRONIC DEVICE FOR LIGHT-EMITTING DISPLAY WITH CONDUCTIVE LIGHT-EMITTING CONFINEMENT WALLS AND CORRESPONDING MANUFACTURING METHOD

摘要

Disclosed is an optoelectronic device (10) for a light-emitting display, which device includes: a substrate (11); a plurality of light-emitting elements (13) electrically connected to at least one first electrode (13d), each light-emitting element (13) comprising at least one light-emitting diode (15) of which a doped portion is placed in electrical contact with said first electrode (13d), said first electrode (13d) covering at least an upper portion of said doped portion placed on the side opposite the face (11a) of the substrate (11); a plurality of light-emitting confinement walls (16) configured so as to be capable of reflecting all or part of the light emitted by at least one of the light-emitting elements (13) and being arranged in such a way as to surround all or part of said at least one of the light-emitting elements (13); the light-emitting confinement walls (16) of the plurality of light-emitting confinement walls (16) being electrically conductive and connected directly to the first electrode (13d).
