| Zusammenfassung: | An organic light emitting display device has an optical multilayer film on an organic light emitting diode. The organic light emitting display device includes an organic light emitting element with a cathode, an anode, and an organic light emitting layer, and an optical multilayer film on the organic light emitting element. The optical multilayer film is constructed such that a full width at half maximum of light emitted from the organic light emitting element is larger than a full width at half maximum of light emitted from a structure in which the optical multilayer film is not used. The color shift depending on a viewing angle of the organic light emitting display device may be reduced to improve efficiency of the organic light emitting element. |
