Abstract: A display panel including first and second sub pixel electrodes, a first light emitting unit, first and second charge generation layers, a second light emitting unit, and an upper electrode. The first light emitting unit is provided with a first contact hole. The first charge generation layer includes a first contact part being in the first contact hole and coupled to a portion of the first sub pixel electrode exposed by the first contact hole, and a first extension part extending from the first contact part and being on the first light emitting unit. The second charge generation layer and the second light emitting unit are provided with a second contact hole. The upper electrode includes a first upper electrode part being in the second contact hole and coupled to a second contact part of the second charge generation layer exposed by the second contact hole.

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).
