Abstract
The invention relates to an organic light-emitting component (), comprising a functional layer stack () between two electrodes (), wherein the functional layer stack () has at least two organic light-emitting layers () and at least one charge carrier generation zone (), which is arranged between the two organic light-emitting layers (), wherein the charge carrier generation zone () comprises an electron-conducting organic layer () and a hole-conducting organic layer (), between which an intermediate region () is arranged, wherein the intermediate region () comprises at least one organic intermediate layer () which has a first charge carrier transport mechanism and an inorganic intermediate layer () which has a second charge carrier transport mechanism, wherein the inorganic intermediate layer () is arranged between the organic intermediate layer () and the electron-conducting organic layer (), and wherein the first charge carrier transport mechanism is at least partially different to the second charge carrier transport mechanism.
