Abstract
An optoelectronic device includes at least one primary sub-pixel having at least one first primary stack with at least two first main layers of indium nitride and gallium nitride, the layers separated in pairs at least by a first intermediate layer of gallium nitride. The device includes a first primary active layer with at least one first quantum well, and a second primary stack having at least two second main layers of indium nitride and gallium nitride the layers separated in pairs by a second intermediate layer of gallium nitride; at least one second primary active layer with one second quantum well; and a first primary junction layer formed on and in contact with the second primary active layer, the first primary junction layer doped according to a second type of doping chosen from an N-type and a P-type dopings, the second type of doping different from the first type.
