Method of manufacturing organic light-emitting display apparatus including multilayer auxiliary electrode

Abstract

A method of manufacturing an organic light-emitting display apparatus includes: forming an auxiliary electrode including: a first conductive layer; and a second conductive layer disposed on the first conductive layer, the second conductive layer having a resistance higher than a resistance of the first conductive layer; forming a first intermediate layer on the auxiliary electrode; exposing the first conductive layer includes forming a first opening in the first intermediate layer and an opening portion in the second conductive layer by removing a portion of the first intermediate layer and a portion of the second conductive layer of the auxiliary electrode; and forming an opposite electrode on the first intermediate layer and the first conductive layer, wherein the opposite electrode is disposed contacting the first conductive layer exposed through the first opening of the first intermediate layer and the opening portion of the second conductive layer.

What is claimed is: 
     
         1 . A method of manufacturing an organic light-emitting display apparatus, the method comprising:
 forming an auxiliary electrode comprising:
 a first conductive layer; and 
 a second conductive layer disposed on the first conductive layer, the second conductive layer having a resistance higher than a resistance of the first conductive layer; 
   forming a pixel electrode, the pixel electrode being electrically insulated from the auxiliary electrode;   forming a first intermediate layer on the pixel electrode and the auxiliary electrode, the first intermediate layer comprising an organic material;   forming an emission layer corresponding to the pixel electrode on the first intermediate layer, wherein the first intermediate layer is interposed between the pixel electrode and the emission layer;   exposing the first conductive layer by forming a first opening in the first intermediate layer and an opening portion in the second conductive layer by removing a portion of the first intermediate layer and a portion of the second conductive layer of the auxiliary electrode; and   forming an opposite electrode on the first intermediate layer and the first conductive layer, wherein the opposite electrode is disposed contacting the first conductive layer exposed through the first opening of the first intermediate layer and the opening portion of the second conductive layer,   wherein a width of the first opening in the first intermediate layer is larger than a width of the opening portion in the second conductive layer.
