Abstract

A method of manufacturing a transparent organic light emitting display apparatus having an emission area, and a transmission area disposed adjacent to the emission area and configured to pass external light therethrough, includes sequentially forming an interlayer dielectric and a first protection layer on a first substrate, patterning a planarization layer over the first protection layer, forming an organic light emitting device over the planarization layer, forming an encapsulation layer and an encapsulation substrate over the organic light emitting device, and exposing and etching at least some portions of the transmission area by using photolithography after the patterning of the planarization layer.
