Abstract: An organic light emitting device having a structure that a plurality of light emitting units are deposited, is disclosed, of which white color shift caused by variation of a viewing angle is reduced through a combination between dopant materials of the respective light emitting units. The organic light emitting device includes dopant materials emitting light of different wavelengths from the plurality of light emitting units. Therefore, in the organic light emitting device, variation of color and luminance, which is perceived by a user as a viewing angle is varied, may be reduced.
