    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.

    Abstract: An organic light-emitting display device characterized by improved reliability is disclosed. The organic light-emitting display device is configured such that each of an organic encapsulation layer, which is disposed on a light-emitting element, and an upper inorganic encapsulation layer, which is disposed on the organic encapsulation layer, are divided into a plurality of parts. Even when cracks are formed in a subpixel due to an external impact or when external moisture or oxygen permeates into the subpixel, therefore, it is possible to prevent the cracks, the moisture, or the oxygen from diffusing to an adjacent subpixel, whereby the reliability and lifespan of the display device are improved.
