Abstract

An electroluminescent layer arrangement having a light-emitting organic material arranged between two electrodes which can be connected to a DC voltage source, a first electrode being a hole-injecting electrode (anode) and a second electrode being an electron-injecting electrode (cathode). The hole-injecting electrode and/or the electron-injecting electrode consist, at least locally, of a nanomaterial.
