Zusammenfassung:An embodiment of the present invention discloses an organic light emitting display device. The organic light emitting display device includes a substrate including a plurality of pixel regions and non-pixel regions inside a display region; a plurality of pixel electrodes corresponding to each of the plurality of pixel regions; a pixel defining layer including a cover part covering edges of the plurality of pixel electrodes and an opening exposing the central portion of the plurality of pixel electrodes; an auxiliary electrode disposed to correspond to at least a part of the upper surface of the cover part; and an intermediate layer and a counter electrode disposed in the opening. The auxiliary electrode is connected to the counter electrode. At least a part of the upper surface of the cover part has an inserted under-cut structure with respect to the auxiliary electrode. It is possible to reduce the incidence of defects in the organic light emitting device. 본 발명의 일 실시예는, 표시영역 내부에 복수의 화소영역 및 비화소영역을 구비한 기판; 상기 복수의 화소영역 각각에 대응하는 복수의 화소전극; 상기 복수의 화소전극의 가장자리를 덮는 커버부 및 상기 복수의 화소전극의 중앙부를 노출하는 개구를 포함하는 화소정의막; 상기 커버부 상면의 적어도 일부에 대응하도록 배치된 보조전극; 및 상기 개구부 내에 배치된 중간층 및 상대전극;을 포함하며, 상기 보조전극은 상기 상대전극과 연결되며, 상기 커버부 상면의 적어도 일부는 상기 보조전극에 대해서 인입된 언더-컷(under-cut) 구조를 구비하는, 유기발광표시장치를 개시한다.
