Реферат: Electroluminescent systems with transparent electrode(s) and a multi-zone electroluminescent element in which the hole-injecting zone contains a neutral or cationic polythiophene and the adjacent hole-conducting zone contains aromatic amine compound(s). Electroluminescent systems contains a substrate, an anode, an electroluminescent (EL) element and a cathode, in which at least one of the two electrodes is transparent or semi-transparent to visible light and the EL element may contain a hole-injecting zone, hole-transporting zone, electroluminescent zone, electron-transporting zone and electron-injecting zone. The hole-injecting zone contains a neutral or cationic polythiophene of formula (I) and the hole-conducting zone adjacent to the hole-injecting zone contains aromatic amine compound(s) (A). Q<1>, Q<2> = H, optionally substituted 1-20C alkyl, CH2OH or 6-14C aryl;, or Q<1> plus Q<2> = -(CH2)m-CH2- or 6-14C arylene; m = 0-12, preferably 1-5; n = 2-10,000, preferably 5-5000
