    Abstract: An organic light emitting diode display is disclosed. The organic light emitting diode display includes a first substrate on which pixels each including an organic light emitting diode are disposed, a second substrate including a power line supplied with a power voltage and facing the first substrate, and a conductive filler layer interposed between the first substrate and the second substrate and including a conductive medium. The first substrate includes an auxiliary electrode, a first barrier disposed on the auxiliary electrode, a cathode divided by the first barrier and exposing at least a portion of the auxiliary electrode, and a protective layer disposed on the cathode, divided by the first barrier, and exposing at least a portion of the auxiliary electrode. One end of the cathode directly contacts the auxiliary electrode.

    Abstract: A top-emissive organic light-emitting diode display includes a substrate, an auxiliary line, an insulating film, an auxiliary cathode, a passivation film, a planarization film, an under-cut opening, an under-area, a connecting terminal, an organic emission layer, and a cathode. An under-cut opening exposes one end of the auxiliary cathode. The under-area is formed inside the under-cut opening by removing the insulating film underlying the exposed end of the auxiliary cathode. The connecting terminal on the planarization film extends to the under-cut opening and makes contact with the exposed auxiliary cathode. The organic emission layer is stacked on the surface of the auxiliary cathode, and is not applied to the under-area and exposes the side of the connecting terminal making contact with the auxiliary cathode. The cathode is stacked on the organic emission layer and makes contact with the side of the connecting terminal not covered by the organic emission layer.
