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 includes 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.

Abstract: A display apparatus includes a substrate having a first area, a second area, and a bending area disposed therebetween. The substrate is bent at the bending area about a bending axis. An inorganic insulating layer is disposed over the substrate and includes an opening or groove corresponding to the bending area. An organic material layer fills the opening or groove. A first conductive layer extends from the first area to the second area through the bending area. The first conductive layer is disposed over the organic material layer and includes a multipath portion having a plurality of through holes. A length of the multipath portion, in a direction from the first area to the second area, is greater than a width of the opening or groove, in the direction from the first area to the second area.
