ORGANIC LIGHT EMITTING DISPLAY DEVICE

摘要

Disclosed is an organic light emitting display device for reducing a color defect or a color difference which occurs in the front or side of the organic light emitting display device. The organic light emitting display device includes a first electrode, a second electrode and an organic layer between the first electrode and the second electrode, the organic layer including at least one emission part. The organic layer is configured for a peak wavelength of an electroluminescence (EL) spectrum of the organic light emitting display device emitted from the at least one emission part to have a range from 10nm less to 10nm more than a predetermined peak wavelength.
