Abstract
A method of manufacturing an organic light-emitting display apparatus including forming a lift-off layer on a substrate including a first electrode, the lift-off layer including a fluoropolymer; sequentially forming a barrier layer and a photoresist on the lift-off layer, the barrier layer including an inorganic material; patterning the photoresist and the barrier layer to remove a first portion of the photoresist corresponding to the first electrode such that a second portion other than the first portion remains; etching a portion of the lift-off layer corresponding to the first portion to expose the first electrode; forming an organic functional layer and an auxiliary electrode over the first electrode and the second portion of the photoresist, the organic functional layer including an emission layer; and removing the lift-off layer, the barrier layer, the photoresist, the organic functional layer, and the auxiliary electrode remaining on the second portion.
