Abstract: An organic light emitting diode display is discussed. The organic light emitting diode display can include a substrate including a thin film transistor region in which a thin film transistor and an organic light emitting diode connected to the thin film transistor are disposed, and an auxiliary electrode region in which an auxiliary electrode is disposed, a barrier disposed on the auxiliary electrode, a cathode included in the organic light emitting diode, divided by the barrier, and exposing at least a portion of the auxiliary electrode, an end of the cathode being in direct contact with the auxiliary electrode, and a cover layer disposed on the cathode, the cover layer having continuity to cover the barrier and the auxiliary electrode.

Abstract: Disclosed is an organic light emitting display device including a passivation layer, a planarization layer, a cover layer, and a bank layer. The passivation film may cover a first area, in which an organic light emitting diode is disposed, and a second area adjacent to the first area. The planarization layer may be disposed on the passivation film in the first area. The cover layer may be disposed to surround the planarization layer on the passivation film. The bank layer may cover at least an edge of an upper part of the planarization layer, and separate the first area.
