Abstract

An organic light-emitting display apparatus includes a substrate having a display area displaying an image and a periphery area. The periphery area is located next to the display area. A first organic insulating layer is disposed on the substrate. The first organic insulating layer includes a valley portion separating the first organic insulating layer from the periphery area. A plurality of organic light-emitting devices is disposed on the substrate. Each of the organic light-emitting devices includes a first electrode, an emission layer, and a second electrode, sequentially disposed over the first organic insulating layer. The second electrode covers the emission layer and the valley portion. A second organic insulating layer is disposed over the first organic insulating layer and incudes a first opening exposing a center portion of the first electrode and a second opening overlapping the valley portion. A capping layer covers the second electrode.

Claims (12)

1. An organic light-emitting display apparatus comprising:

a substrate having a display area, within which an image is displayed using a plurality of organic light-emitting devices;

a valley portion disposed on the substrate outside of the display area, the valley portion separating a region of an organic insulating layer;

a power supply line disposed on the substrate outside of the display area and supplying power to the plurality of organic light-emitting devices;

a dam portion disposed on the substrate outside of the display area;

a common electrode of the plurality of organic light-emitting devices, covering the display area and the valley portion, and contacting the power supply line;

a capping layer covering the common electrode; and

an encapsulation member disposed over the capping layer and comprising at least one organic film and at least one inorganic film.

2. The organic light-emitting display apparatus of claim 1 , further comprising a connection conductive layer disposed outside of the display area and connecting the common electrode and the power supply line.

3. The organic light-emitting display apparatus of claim 1 , wherein the at least one organic film of the encapsulation member is disposed in the display area and inside of the dam portion.

4. The organic light-emitting display apparatus of claim 1 , wherein the at least one inorganic film of the encapsulation member covers the display area and the dam portion, and extends outside of the dam portion.

5. The inorganic light-emitting display apparatus of claim 1 , wherein the dam portion comprises a first dam portion and a second dam portion disposed outside of the first dam portion.
