Abstract: Disclosed is an organic light emitting display device. The organic light emitting display device includes a substrate, a thin film transistor formed on the substrate, a first electrode formed on the thin film transistor, an organic emission layer, and a second electrode formed on the organic emission layer. The organic emission layer includes a first stack that includes a first emission layer formed on the first electrode to emit first color light, a second stack that includes a second emission layer formed on the first electrode to emit second color light, and a charge generation layer formed between the first and second stacks.
