Electroluminescent assemblies containing a substrate, an anode, an electroluminescent element and a cathode, where at least one of the two electrodes is transparent or semitransparent in the visible spectral region and the electroluminescent element can contain in order: a hole injection zone, a hole transport zone, an electroluminescent zone, an electron transport zone and an electron injection zone, characterized in that the hole injection zone contains an uncharged or cationic polythiophene of the formula (I), where Q1 and Q2 represent, independently of one another, hydrogen, substituted or unsubstituted (C1-C20)-alkyl, CH2OH or (C6-C14)-aryl or Q1 and Q2 together represent -(CH2)m-CH2- where m=0 to 12, preferably 1 to 5, (C6-C14)-arylene, and n represents an integer from 2 to 10,000, preferably from 5 to 5000, and the hole transport zone adjoining the hole injection zone contains one or more aromatic amine compounds.
