Abstract: An organic light emitting device is provided which comprises a substrate (60), an anode contact electrode (64), a cathode contact electrode (61), and an organic region (62, 63) in which electroluminescence takes place if a voltage is applied between said anode (64) and cathode (61). At least one of said electrodes (61, 64) comprises a non-degenerate wide bandgap semiconductor.
