Abstract: An organic light emitting device includes a base substrate having a pixel region and a non-pixel region, an organic light emitting element on the pixel region, and an auxiliary line in the non-pixel region. The organic light emitting element includes an anode, a first organic light emitting layer disposed on the anode, a first cathode, and a second cathode. The first cathode is on the first organic light emitting layer to be thereby electrically connected to the auxiliary line. The second cathode is on the first cathode to be thereby electrically connected to the first cathode. The first cathode may include a metal and the second cathode may include a transparent conductive oxide (TCO).
