Abstract:
Disclosed herein are an organic light emitting display device includes first to third sub-pixels realizing different colors, wherein each of the first to third sub-pixels includes first and second electrodes disposed on a substrate so as to face each other, an emission layer formed between the first and second electrodes, a multi-layered hole transporting layer formed between the first electrode and the emission layer to be in contact with the first electrode and the emission layer, and an electron transporting layer formed between the second electrode and the emission layer, wherein multi-layered hole transporting layer of at least one of the first to third sub-pixels includes an at least two-layered first hole transporting layer formed of a hole host and a p-type dopant having a doping concentration of 1 to 10% and a second hole transporting layer formed of the hole host.
