Abstract: An organic light-emitting display device includes: an auxiliary line disposed between a plurality of sub-pixels, an auxiliary line connection part connected to the auxiliary line, a passivation layer disposed on the auxiliary line connection part and configured to expose a part of the auxiliary line connection part in a contact area, an interlayer insulation layer disposed between the auxiliary line and the passivation layer. The auxiliary line connection part includes: a first auxiliary line connection part disposed below the interlayer insulation layer and connected to the auxiliary line, and a second auxiliary line connection part disposed between the interlayer insulation layer and the passivation layer and connected to the first auxiliary line connection part. A cathode electrode of each of the plurality of organic light-emitting elements disposed on the plurality of sub-pixels is in contact with the auxiliary line connection part in the contact area.
