The organic light-emitting display apparatus includes further an interlayer insulating layer on the pad electrode, a conductive barrier layer, and a planarization insulating layer. The interlayer insulating layer includes a plurality of openings that expose an upper surface of the pad electrode. The conductive barrier layer is on the plurality of openings and the interlayer insulating layer. The planarization insulating layer covers an edge of the conductive barrier layer. The planarization insulating layer is in the openings and covers an edge of the conductive barrier layer. An upper portion of the planarization insulating layer may be substantially planar with an upper portion of the conductive barrier layer on convex portions of the interlayer insulating layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pad electrode structure and organic light-emitting display apparatus including the pad electrode structure","description":"An organic light-emitting display apparatus includes a pad electrode structure having excellent reliability due to the prevention of propagation of a crack to the pad electrode.
