Abstract
An organic light emitting display device includes a first electrode formed on a substrate and being a reflective electrode, a second electrode facing the first electrode and being a semi-transparent electrode, and red, green and blue emission layers formed between the first and second electrodes, wherein a maximum electroluminescent peak of the redemission layer and a maximum photoluminescence peak of a host included in the red emission layer satisfy Equation 1 below:REDELλmax−RHPLλmax≧120 nm <Equation 1>wherein REDELλmax is a maximum electroluminescent peak of the red emission layer, and RHPLλmax is a maximum photoluminescence peak of a red host included in the red emission layer.
