Summary:PURPOSE: A white organic light emitting display device is provided to improve a color viewing angle by forming a stack for emitting the long wavelength of light on a positive electrode, and a stack for emitting the short wavelength of light on a negative electrode. CONSTITUTION: A first electrode (210) and a second electrode (250) are formed on a substrate. The first electrode faces the second electrode. A charge generation layer (230) is formed between the first electrode and the second electrode. A first stack (220) is formed between the first electrode and the charge generation layer. A second stack (240) is formed between the charge generation layer and the second electrode. The wavelength of light emitted from the first stack is longer than the wavelength of light emitted from the second stack.
