Abstract
A method of manufacturing an organic light-emitting display device includes: preparing a substrate including pixel electrodes; forming a pixel defining layer on the substrate, the pixel defining layer exposing a central portion of each of the pixel electrodes and covering an edge portion of each of the pixel electrodes; forming partitioning walls in correspondence with at least a portion of an upper surface of the pixel defining layer, the partitioning walls including a first resin; removing a solvent in the partitioning walls by baking the partitioning walls; forming a first mask layer filling a space between the partitioning walls and exposing a first pixel electrode among the pixel electrodes, the first mask layer including a second resin; and forming a first intermediate layer on the first pixel electrode.
