The organic light emitting display device includes opposite first and second electrodes on a substrate and a plurality of emission parts between the first and second electrodes. At least one among the plurality of emission parts includes a first emission layer and a second emission layer having different wavelength ranges. A dopant content in the first emission layer is lower than a dopant content in the second emission layer.
