Patent ID: 8823019

Claim:
A white organic light emitting device comprising: a first electrode and a second electrode disposed opposite each other on a substrate, and a blue light emitting unit and a phosphorescent light emitting unit provided between the first electrode and the second electrode, wherein a white spectrum of the white organic light emitting unit has only 2 peaks and the 2-peaked white spectrum is formed through a first light emitting peak of the blue light emitting unit at a wavelength of 430 nm to 460 nm and a second light emitting peak of the phosphorescent light emitting unit at a wavelength of 530 nm to 630 nm such that a value of a CIEy color coordinate of blue light after transmission through a color filter via the blue light emitting unit and the phosphorescent light emitting unit is less than or equal to 0.06, wherein the maximum peak of the 2-peak white spectrum is generated at a wavelength corresponding to the first light emitting peak, and wherein a trough of the 2-peak white spectrum between the first light emitting peak and the second light emitting peak is at a wavelength of 480 nm to 530 nm.
