Abstract: A method of manufacturing an organic light-emitting display apparatus includes the step of forming a first pixel electrode and a second pixel electrode on a substrate, forming a pixel-defining film on the first pixel electrode and the second pixel electrode, the pixel-defining film having an opening through which each of the first pixel electrode and the second pixel electrode is exposed, forming a first masking pattern on the pixel-defining film having a first opening portion through which the first pixel electrode is exposed, sequentially forming a first intermediate layer including a first emission layer, a first counter electrode, a first protective layer, and a first anti-decapping layer on the first pixel electrode and the first masking pattern, and removing the first masking pattern along with the first intermediate layer, the first counter electrode, the first protective layer, and the first anti-decapping layer disposed on the first masking pattern.
