## 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

### Claim 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.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 1)

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.

### Claim 4 (depends on 1)

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.

### Claim 5 (depends on 1)

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.
