    摘要： 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.

    摘要： An organic light emitting display device and a light apparatus for vehicles using the same are provided. The organic light emitting display device includes a first layer on a first electrode, a second layer on the first layer, a second electrode on the second layer, and an N-type charge generation layer between the first layer and the second layer. The first layer includes a first emission layer and a first electron transport layer, and the second layer includes a second emission layer and a second electron transport layer. A low unoccupied molecular orbitals (LUMO) level of the first electron transport layer is higher than a LUMO level of a host included in the N-type charge generation layer.
