Abstract
An organic light emitting display includes a substrate; a first pixel electrode disposed on the substrate; a second pixel electrode disposed on the substrate; a hole auxiliary layer disposed on the first pixel electrode and the second pixel electrode; a first organic emission layer disposed on the hole auxiliary layer in correspondence with the first pixel electrode and the second pixel electrode; a blue organic emission layer disposed on the hole auxiliary layer in correspondence with the first pixel electrode and the second pixel electrode, the blue organic emission layer being further disposed on the first organic emission layer; a non-doping blue organic emission layer disposed on the blue organic emission layer; an electron auxiliary layer disposed on the non-doping blue organic emission layer; and a common electrode disposed on the electron auxiliary layer.
