The above objects have been accomplished by providing an OLED having an organic active (53) region with at least one emission layer (EL). The OLED further comprises at least one organic charge transport layer (52) (either a hole transport layer or an electron transport layer), an anode (51) and a cathode (54). This organic charge transport layer (52) is alloyed by introduction of an inorganic component. If said alloyed charge transport layer (52) is a hole transport layer (HTL), for example, the holes are conducted through it by means of the inorganic constituents with reduced voltage drop or heating.
