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.
