Abstract: A display apparatus includes a substrate, a wire having an inner edge including first and second portions, a first insulating layer covering a portion of the substrate, and a second insulating layer. The portion of the substrate covered by the first insulating layer is closer to a center of the substrate than the wire, the first insulating layer covers a part of the first portion of the wire and a part of the second portion of the wire, and a first end of the first insulating layer is disposed on the wire. The second insulating layer covers the first insulating layer and has a second end disposed on the wire. A distance between the first end and the second end covering the first portion of the wire is different from a distance between the first end and the second end covering the second portion of the wire.

Abstract: A display device includes a substrate including a bending area located between a first area and a second area. The substrate is bent in relation to a bending axis. A first wiring unit including a plurality of first wirings is arranged on the substrate to sequentially extend over the first area, the bending area, and the second area. First central axes included in each of the plurality of first wirings are spaced apart from each other by a first pitch in the bending area. A second wiring unit including a plurality of second wirings is arranged on the substrate to sequentially extend over the first area, the bending area, and the second area. Second central axes included in each of the plurality of second wirings are spaced apart from each other by a second pitch greater than the first pitch in the bending area.
