Abstract
Official abstract text for this publication.
An organic light-emitting display apparatus and a method of manufacturing the same. The organic light-emitting display apparatus includes an organic light-emitting device in which a pixel electrode, an intermediate layer that includes an emissive layer, and a cathode electrode are sequentially stacked. The cathode contact unit includes a cathode bus line that is formed on the same layer as the pixel electrode and contacts the cathode electrode, a first auxiliary electrode that is formed on the cathode bus line along an edge area of the cathode bus line, and a second auxiliary electrode that contacts the first auxiliary electrode.
