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.

Abstract: A display device includes a substrate divided into an encapsulation area and a non-encapsulation area. The display device includes an interlayer insulating layer disposed over the substrate. The display device includes a first inner contact hole passing through the interlayer insulating layer in the encapsulation area, and connecting an inner conductive layer to an inner lower conductive layer. The display device includes an outer contact hole passing through the interlayer insulating layer in the non-encapsulation area, and connecting an outer conductive layer to an outer lower conductive layer. A slope angle formed by a lateral wall of the outer contact hole with respect to an upper surface of the substrate is less than a slope angle formed by a lateral wall of the first inner contact hole with respect to the upper surface of the substrate.
