Abstract: Disclosed are an organic light-emitting device and a method of manufacturing the same. In the organic light-emitting device, an auxiliary electrode is formed on anode electrode to come into contact with the anode electrode via the same mask process as the anode electrode, which results in a simplified structure and simplified processing. In addition, a bank is disposed to cover a side surface and an upper surface of the auxiliary electrode and a side surface of the anode electrode, whereby damage to the auxiliary electrode and the anode electrode is prevented.
