Abstract: A method of manufacturing an organic light emitting display apparatus includes preparing a substrate having a pixel electrode and a pixel defining layer exposing the pixel electrode, forming a hole injection layer (HIL) on the substrate to cover the pixel electrode and the pixel defining layer, forming a primer layer on the HIL, patterning the primer layer to leave a region corresponding to at least a portion of the pixel electrode, removing a portion of the HIL to expose an outer portion of the substrate, and forming an opposing electrode to cover the HIL and the outer portion of the substrate.

Abstract: A method of manufacturing an organic light emitting structure is provided as follows. A first electrode is formed on a lower substrate. A pixel defining layer is formed adjacent to the first electrode on the lower substrate. A preliminary charge transport layer is formed on the first electrode and the pixel defining layer. An organic light emitting layer is formed on the preliminary charge transport layer. The preliminary charge transport layer is selectively etched to form a charge transport layer. A second electrode is formed on the organic light emitting layer.
