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.

Abstract: A method of manufacturing an organic light-emitting display apparatus including: forming a lift-off layer including a fluoropolymer, a barrier layer having a higher fluorine content than the lift-off layer, and a photoresist on a substrate including a first electrode; removing a portion corresponding to the first electrode by patterning the photoresist, and leaving the remaining portion; exposing the first electrode by etching the lift-off layer and the barrier layer on the first electrode; forming an organic functional layer on the first electrode and on the remaining photoresist; removing the barrier layer, the photoresist, and the organic functional layer on the remaining lift-off layer; and forming a second electrode on the organic functional layer on the first electrode.

Abstract: A method of manufacturing an organic light-emitting display apparatus includes forming a first lift-off layer comprising fluoropolymer and a moisture absorbent over a substrate comprising a first electrode; forming a photoresist over the first lift-off layer and patterning the photoresist by removing a part of the photoresist; etching the first lift-off layer in a region from which the part of the photoresist has been removed by using a first solvent to expose the first electrode; forming an organic functional layer comprising an emission layer above the first electrode and above the first lift-off layer; removing the first lift-off layer by using a second solvent; and forming a second electrode over the organic functional layer.
