摘要： The invention relates to a polychromatic electronic display device with an electroluminescent screen, particularly with organic light-emitting diodes (OLEDs), wherein the polychromatic electronic display device comprises an electroluminescent emission surface and, towards the inside of the device, at least one substrate (2) coated with a pixel matrix, said device including a stack of a plurality of electroluminescent cells (UI and Ue) in which each pixel comprises at least three sub-pixels having different colours. According to the invention, for each pixel, the sub-pixel having the lowest emission wavelength λc, or critical sub-pixel, is exclusively located in the external unit (Ue) adjacent to said emission surface, each of the other sub-pixels emitting at a wavelength higher than λc being exclusively located in an internal unit (UI) relative to said external unit and adjacent to the substrate, the surface area of this critical sub-pixel being higher than that of each of the other sub-pixels.
