Abstract
Provided are a method of manufacturing an organic light emitting display apparatus, a surface treatment device for an organic light emitting display apparatus, and an organic light emitting display apparatus. To easily form organic emissive layers, the method includes: forming a first electrode on a substrate; forming on the first electrode a pixel defining layer having openings that expose predetermined portions of the first electrode; forming a charge carrying layer on the pixel defining layer and the first electrode exposed through the openings; hydrophobically treating portions of a surface of the charge carrying layer selectively, wherein the portions do not correspond to the openings, using a laser; forming organic emissive layers on the charge carrying layer; and forming a second electrode on the organic emissive layers so as to be electrically connected with the organic emissive layers.
