Patent ID: 8420423

Claim:
A method of manufacturing an organic light-emitting display apparatus, the method comprising: sequentially forming a planarization layer, a metal layer, a reflective layer, a first transparent conductive layer, and a second transparent conductive layer in the stated order on a substrate; patterning the reflective layer, the first transparent conductive layer, and the second transparent conductive layer through a photoresist pattern to define separate stack structures; removing the photoresist pattern by plasma ashing; patterning the metal layer, after the plasma ashing, to form the stack structures into a plurality of group electrode layers having different numbers of layers on the planarization layer, the plurality of group electrode layers being spaced apart from one another by a predetermined distance and including: a first group electrode layer having a metal layer, a reflective layer, a first transparent conductive layer, a second transparent conductive layer, and a third transparent conductive layer sequentially stacked in the stated order, a second group electrode layer having the metal layer, the reflective layer, the first transparent conductive layer, and the third transparent conductive layer sequentially stacked in the stated order, and a third group electrode layer having the metal layer, the reflective layer, and the first transparent conductive layer sequentially stacked in the stated order; forming an intermediate layer on the first group electrode layer, the second group electrode layer, and the third group electrode layer, and including at least one organic light-emitting layer; and forming a second electrode layer on the intermediate layer.
