Abstract

A method of manufacturing an organic light-emitting display apparatus includes forming a pixel electrode and a pixel-defining layer on a substrate, the pixel-defining layer covering edges of the pixel electrode sequentially forming a lift-off layer and a photoresist on the pixel electrode and the pixel-defining layer patterning the lift-off layer and the photoresist to define an opening that exposes a top surface of the pixel electrode and a portion of the pixel-defining layer sequentially forming an intermediate layer and an opposite electrode in the opening and on the photoresist, the intermediate layer including an emission layer forming a passivation layer to cover an entirety of a top surface and end portions of the opposite electrode and removing the lift-off layer and the photoresist that remain outside the opening.
