Abstract: An electroluminescence color display screen comprising an organic electroluminescence layer disposed between a patterned base electrode layer and a patterned top electrode layer, and further comprising a color conversion layer and a spectrally selective reflector for improving the color efficiency of the color display screen.

Abstract: Electroluminescence color display screen with matrix picture elements (pixels), the display screen comprising a system of single layers applied on top of and partially next to one another, the layer system comprising an insulating, optically at least translucent base layer, a conductive, optically at least translucent base electrode, a patterned electrically insulating intermediate layer, if necessary, one or several color conversion layers applied in form of a matrix and, if necessary, one or several index matching layers, wherein the base electrode is deposited as a continuous layer upon the entire area of the base layer, wherein the insulating intermediate layer encloses and projects past pixel areas made of the organic electroluminescence layer and arranged to form a matrix, and wherein the top electrode applied on top of each pixel area extends partially across the adjacent lattice wall.
