More Information
Summary:Provided is an organic light emitting display device capable of improving efficiency, color reproducibility, and a rate of change in color by reducing the rate of change in color according to a viewing angle by optimizing the thickness of organic layers forming light emitting units. The organic light emitting display device comprises: first and second electrodes facing each other on a substrate; and at least three light emitting units between the first and second electrodes. A first distance between the substrate and a first light emitting layer, a second distance between the first light emitting layer and a second light emitting layer, a third distance between the second light emitting layer and a third light emitting layer, and a fourth distance between the third light emitting layer and the second electrode are configured to be different from each other. 본 발명의 유기발광 표시장치는 기판 위에 서로 대향하는 제1 전극 및 제2 전극과, 상기 제1 전극과 제2 전극 사이에 있는 적어도 세 개의 발광부를 포함하며, 상기 기판과 상기 제1 발광층 사이의 제1 거리, 상기 제1 발광층과 상기 제2 발광층 사이의 제2 거리, 상기 제2 발광층과 상기 제3 발광층 사이의 제3 거리, 및 상기 제3 발광층과 상기 제2 전극 사이의 제4 거리가 각각 서로 다르도록 구성한다.
