Organic light-emitting display apparatus and method of manufacturing the same

A method of manufacturing an organic light-emitting display apparatus, the method comprising:

• forming a plurality of first electrodes over a substrate and performing a first unit process comprising following operations (a1) through (e1);
• (a1) forming a first lift-off layer comprising fluoropolymer over the substrate comprising the plurality of first electrodes;
• (b1) forming a photoresist over the first lift-off layer and patterning the photoresist by removing a part of the photoresist;
• (c1) etching the first lift-off layer in a region from which the photoresist has been removed by using a first solvent to expose a predetermined first electrode selected from the plurality of first electrodes;
• (d1) forming a first organic functional layer comprising an emission layer above the predetermined first electrode and above the first lift-off layer;
• (e1) removing the first lift-off layer by using a second solvent;
• after performing the first unit process, performing a second unit process comprising following operations (a2) through (e2) at least one time;
• (a2) forming a second lift-off layer comprising fluoropolymer and a moisture absorbent over the substrate comprising the plurality of first electrodes;
• (b2) forming a photoresist over the second lift-off layer and patterning the photoresist by removing a part of the photoresist;
• (c2) etching the second lift-off layer in a region from which the photoresist has been removed by using the first solvent to expose a first electrode different from the predetermined first electrode selected during the first unit process;
• (d2) forming a second organic functional layer comprising an emission layer above the first electrode and above the second lift-off layer;
• (e2) removing the second lift-off layer by using the second solvent;
• and
• after performing the first unit process and the second unit process, forming a second electrode.
