Abstract
A method of manufacturing an organic light-emitting display apparatus includes: forming a lift-off layer on a substrate including a first electrode, the lift-off layer including a fluoropolymer; forming a pattern layer on the lift-off layer; etching the lift-off layer between patterns of the pattern layer by utilizing a first solvent to expose the first electrode; forming an organic functional layer on the first electrode and the pattern layer, the organic functional layer including an emission layer; removing remaining portions of the lift-off layer by utilizing a second solvent; and forming a second electrode on the organic functional layer.
