Abstract: 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.

Abstract: A substrate for an organic light emitting display device and an organic light emitting display device are provided. The substrate to the organic light emitting display device includes a protective layer having a non-flat shape; a first electrode on the protective layer and having the non-flat shape; and a bank layer on the protective layer and the first electrode. The bank layer having an opening for exposing the first electrode. The protective layer is formed at the opening of the bank layer and a part of an area with the bank layer.
