Abstract:
1. An organic light-emitting display apparatus comprising: a substrate; an organic light-emitting device on the substrate, the organic light-emitting device comprising a first electrode, a second electrode, and an organic light-emitting layer between the first electrode and the second electrode; and a pixel define layer on the first electrode, the pixel define layer comprising an opening through which the first electrode is exposed and having a black color, wherein the first electrode is an anode and the second electrode is a cathode, wherein the first electrode is electrically coupled to a transistor by a contact hole, wherein the pixel define layer substantially covers the contact hole and the transistor, wherein the organic light-emitting layer and the second electrode are sequentially disposed on a portion of the first electrode exposed through the opening, and wherein the second electrode comprises indium oxide doped with a metal or metal oxide.
