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

• forming, on a substrate, a first pixel electrode and a second pixel electrode;
• exposing upper surfaces of the first and second pixel electrodes;
• forming a pixel defining layer covering edges of the first and second pixel electrodes;
• performing a first unit process, the first unit process comprising:
• sequentially forming, on the first and second pixel electrodes and the pixel defining layer, a first lift-off layer, a first shape memory alloy layer, and a first photoresist;
• forming a first opening exposing an upper surface of the first pixel electrode by patterning the first lift-off layer, the first shape memory alloy layer, and the first photoresist;
• forming, on the first pixel electrode and the first photoresist, a first organic functional layer including a first emission layer;
• deforming an end portion of the first shape memory alloy layer, in the first opening, in a direction away from a horizontal surface of the substrate, and forming a first protection layer on the first organic functional layer;
• and
• removing a remainder of the first lift-off layer, and
• after performing the first unit process, performing a second unit process, the second unit process comprising:
• sequentially forming a second lift-off layer, a second shape memory alloy layer, and a second photoresist, on the first organic functional layer, the second pixel electrode, and the pixel defining layer;
