Abstract: An organic light emitting display device comprises first and second electrodes facing each other on a substrate; and three emission portions arranged between the first electrode and the second electrode, wherein at least one among the three emission portions includes two emitting layers, and the first, second and third emission portions being collectively configured as a TOL-FESE (Thickness of Organic Layers between the First Electrode and the Second Electrode) structure in which thicknesses of organic layers between the first electrode and the second electrode are different from one another, each organic layer having a specified thickness that provides the organic light emitting display device having the TOL-FESE structure with improved red efficiency or blue efficiency and minimized color shift rate with respect to a viewing angle, when compared to an organic light emitting display device that lacks the TOL-FESE structure.
