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.

Abstract: Disclosed is an electroluminescent display device (100) comprising a plurality of pixels (120) disposed on a substrate (110), each pixel being formed by one or more basic emitting zones (121a, b, c), every basic emitting zone having a base electrode (102a, b, c) disposed on said substrate (110) and an OLED stack (105) comprising an electroluminescent layer disposed on said base electrode (102a, b, c), the device (100) further comprising a common electrode (107) disposed on top of the OLED stack, said device being characterized in that: —two adjacent base electrodes (102a, 102b) belonging to two adjacent basic emitting zones (121a, b) are separated by a filler element having an insulating surface (103) which fills the zone (111) between said adjacent base electrodes (102a, 102b) and electrically insulates them from each other; at least the surface of said filler element having an insulating surface (103) in contact with the base electrodes (102a, 102b) is made of an insulating material; a separator (104) is si
