Abstract: An organic light emitting display device is disclosed that includes a substrate on which a first sub pixel configured to emit a first color, a second sub pixel configured to emit a second color, and a third sub pixel configured to emit a third color are disposed, a first electrode that defines emitting areas of the first sub pixel, the second sub pixel, and the third sub pixel and is disposed on the substrate, an organic light emitting diode on the first electrode, a bank that defines the emitting areas of the first sub pixel, the second sub pixel, and the third sub pixel and is disposed in a non-emitting area and exposes an upper portion of the first electrode and a second electrode on the organic light emitting diode. The organic light emitting diode includes a path blocking layer in the non-emitting area.

Abstract: Disclosed is an organic light emitting display device that comprises a first light emitting unit between a first electrode and a second electrode, the first light emitting unit including a first hole transporting layer and a first light emitting layer; and a second light emitting unit between the first light emitting unit and the second electrode, the second light emitting unit including a second hole transporting layer and a second light emitting layer that emits a light of the same color as a light emitted by the first light emitting layer. An increase in driving voltage caused by a shift of an emission zone in the first light emitting layer or the second light emitting layer by prolonged driving is minimized which solves a problem of increased power consumption and improves the lifetime of the organic light emitting display device.
