A display device can include a substrate provided with a first subpixel, a first electrode including a first sub electrode provided on the first subpixel, an organic light emitting layer including first and second organic light emitting layers arranged on the first sub electrode and a second organic light emitting layer arranged on the second sub electrode, a second electrode arranged on the organic light emitting layer, and an auxiliary electrode arranged between the first organic light emitting layer on the first sub electrode and the second organic light emitting layer on the first sub electrode, wherein the auxiliary electrode is connected with the second electrode. Therefore, although the first subpixel has a two-stack structure, the organic light emitting layer can emit light in accordance with a voltage of one-stack, whereby overall power consumption can be reduced.
