ABSTRACT:
An organic electroluminescent component with a layer arrangement includes a first electrode layer, an inorganic layer which conducts electrons, one or several optoelectronically active layers with at least one light-emitting layer which comprises an organic emitter, and a second electrode layer. The inorganic layer which conducts electrons is an N-type conducting oxide of a transition metal chosen from the group consisting of zirconium oxide, hafnium oxide, vanadium oxide, barium titanate, barium-strontium titanate, strontium titanate, calcium titanate, calcium zirconate, potassium tantalate, and potassium niobate.
