Abstract

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.
