Summary:The present invention provides an organic light emitting diode display device. The organic light emitting diode display device includes a substrate; a thin film transistor in the upper part of the substrate; a first electrode connected to a drain electrode of the thin film transistor; a bank layer which covers the edge of the first electrode, and has a transmission hole corresponding to the first electrode; a light emitting layer located in the upper part of the first electrode in the transmission hole; a second electrode in the upper part of the light emitting layer; an auxiliary electrode which is located in the upper part of the bank layer, and touches the second electrode; and a capping layer which is located in the upper part of the second electrode except the auxiliary electrode. So, the organic light emitting diode display device with large size, high resolution, and uniform brightness can be provided. 본 발명은, 기판과, 상기 기판 상부의 박막트랜지스터와, 상기 박막트랜지스터의 드레인 전극과 연결되는 제1전극과, 상기 제1전극의 가장자리를 덮으며, 상기 제1전극에 대응하는 투과홀을 갖는 뱅크층과, 상기 투과홀 내의 상기 제1전극 상부에 위치하는 발광층과, 상기 발광층 상부의 제2전극과, 상기 뱅크층 상부에 위치하고, 상기 제2전극과 접촉하는 보조전극과, 상기 보조전극을 제외한 상기 제2전극 상부에 위치하는 캐핑층을 포함하는 것을 특징으로 하는 유기발광다이오드 표시장치를 제공한다.
