Optoelectronic device comprising pixels which emit three colours

An optoelectronic device comprising at least one pixel, said at least one pixel including at least one primary sub-pixel comprising at least one primary light-emitting diode adapted to emit a first light radiation substantially having a first wavelength and formed on a support surface of a substrate, the primary sub-pixel comprising:

• at least one first primary stack including at least two first main layers of indium and gallium nitride meeting the formula InzGa1-zN where 0≤z<0.1, separated two-by-two at least by a first intermediate layer of gallium nitride, at least one of the first main layers being doped according to a first doping type selected amongst a N-type doping and a P-type doping, all or part of the first primary stack being formed over all or part of the support surface;
• at least one first primary active layer totally or partially formed over all or part of the first primary stack, said at least one first primary active layer including at least one first quantum well;
• at least one second primary stack totally or partially formed over all or part of the first primary active layer and including at least two second main layers of indium and gallium nitride meeting the formula InxGa1-xN where 0.1≤x<0.2, separated two-by-two at least by a second intermediate layer of gallium nitride, at least one of the second main layers being doped according to said first doping type selected amongst a N-type doping and a P-type doping;
• at least one second primary active layer totally or partially formed over all or part of the second primary stack and including at least one second quantum well;
• and
• a first primary junction layer formed over the second primary active layer and in contact with the second primary active layer, the first primary junction layer being doped according to a second doping type selected amongst a N-type doping and a P-type doping where the second doping type and different from said first doping type, such that the second primary active layer is adapted to emit said first light radiation.
