Abstract
Disclosed is an organic light-emitting display device configured such that the undercut shape of an auxiliary electrode is improved and such that a region where the auxiliary electrode and a second electrode contact is filled with an inorganic film, whereby a gap is prevented from being formed and the reliability of the organic light-emitting display device is improved. The organic light-emitting display device includes a first electrode located on a substrate defined by an active area and a non-active area, an organic layer including an emissive layer located on the first electrode, a second electrode located on the organic layer, an auxiliary electrode located in the non-active area, and a passivation layer located on the auxiliary electrode, the passivation layer having a reverse taper-shaped end so as to be exposed to the side surface of the auxiliary electrode. The second electrode extends to the non-active area so as to be electrically connected to the exposed auxiliary electrode. In addition, the auxiliary electrode has a taper-shaped end under the passivation layer.
