US Patent 10236328 Method of manufacturing organic light-emitting display device

A method of manufacturing an organic light-emitting display device includes forming pixel electrodes on a substrate, forming a first protective layer with a first exposure portion that exposes a first pixel electrode of the pixel electrodes, forming on the first pixel electrode a first intermediate layer and a first blocking layer covering the first intermediate layer, removing the first protective layer, forming a second protective with a second exposure portion that exposes a second pixel electrode of the pixel electrodes, forming on the first pixel electrode a second intermediate layer and a second blocking layer covering the second intermediate layer, removing the second protective layer, forming a third protective with a third exposure portion that exposes a third pixel electrode of the pixel electrodes, and forming a third intermediate layer on the third pixel electrode, wherein each of the first and second blocking layers includes a self-assembled monolayer.
