Abstract:
Disclosed herein is a white organic light emitting device including various emission layers with improved luminous efficiency, an increased color viewing angle, and low power consumption. The white organic light emitting device includes at least two charge generation layers and at least three stacks between a first electrode and a second electrode. The first stack includes an emission layer having a wavelength range of about 440 to about 470 nm, the second stack includes an emission layer having a wavelength range of about 530 to about 570 nm, and the third stack includes an emission layer having a wavelength range of about 590 to about 620 nm and an emission layer having a wavelength range of about 440 to about 470 nm.
