Abstract
An optoelectronic device that includes a substrate and a stack of organic layers that has at least one active layer arranged between a reflective surface and a semi-reflective surface arranged facing one another at a given distance and forming an optical cavity. The device includes at least three groups of pixels, each group of which is characterized by a cavity of a different optical length, the cavity having a number of bilayers arranged between the substrate and said stack of organic layers, each bilayer being formed of a first transparent and conductive layer of a first transparent and conductive material, and of a second transparent and conductive layer of a second transparent and conductive material, in direct contact with the first transparent and conductive layer.
