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: Disclosed is an organic light-emitting display device that is capable of preventing the reflection of light incident from outside and improving transparency when a transparent display is realized. The organic light-emitting display device includes a first substrate defined by a transmission area and a light emission area, a first electrode located on a region of a planarization film, which covers a thin film transistor, corresponding to the light emission area, the first electrode being electrically connected to the thin film transistor, and a shielding layer located to cover a region of the planarization film corresponding to the transmission area and the side surface of the planarization film, the shielding layer being electrically isolated from the first electrode. A black bank is provided between the transmission area and the emission area so as to cover the edge of the first electrode, and an organic light emissive layer and a second electrode, which covers the organic light emissive layer, are sequentially formed on the first electrode.
