Zusammenfassung:An organic light emitting display device includes first and second electrodes facing each other on a substrate, a charge generation layer formed between the first and second electrodes, a first light emitting stack formed between the charge generation layer and the first electrode, and a second light emitting stack formed between the charge generation layer and the second electrode, wherein a hole injection layer of a light emitting stack to realize blue color of the first and second light emitting stacks is formed by doping a host formed of hexaazatriphenylene (HAT-CN) with 0.5% to less than 10% of a dopant formed of a hole transporting material based on a volume of the hole injection layer.
