An organic light emitting device is provided which comprises a cathode (51), an anode (48, 47, 46), and an organic region (50, 49) in which electroluminescence takes place if a voltage is applied between said anode and cathode. The anode comprises a metal layer (46), a barrier layer (47), and an anode modification layer (48). Light is emitted through the cathode (51). |
