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.

Abstract: An organic light emitting display device secures an auxiliary electrode with a sufficient area without forming a passivation layer, an additional planarization film, an additional connection electrode and an auxiliary electrode. Accordingly, manufacturing of a top-emission organic light emitting display device may use three to four fewer masks, thus advantageously simplifying the process and reducing manufacturing costs, the thickness of the organic light emitting display device and the resistance of the second electrode.
