Abstract: An organic light emitting display element includes a substrate, a lower electrode positioned on the substrate, at least one organic light emitting layer positioned on the lower electrode, a metal doped layer positioned on the organic light emitting layer, and an upper electrode positioned on the metal doped layer that includes a conductive material, and is configured to transmit light. Such organic light emitting display element is capable of minimizing degeneration and damage to the organic light emitting layer caused by sputtering.
