Electroluminescent arrangements, composed of a substrate, an anode, an electroluminescent element and a cathode, at least one of the two electrodes being transparent in the spectral range and it being possible for the electroluminescent element to contain the following zones: (1) a hole-injecting zone, (2) hole-transporting zone, (3) electroluminescent zone, (4) electron-transporting zone and/or (5) an electron-injecting zone, and at least one quinacridone which has sufficient solubility for a casting process is present in at least one of said zone and with the proviso that if more than one zone is present then the zones would be in the following order of (1) to (5) providing the zone is present.
