Abstract: An organic light-emitting display device includes a base substrate, a pixel array, a first power voltage wiring and a second power voltage wiring. The base substrate includes a pixel area and a peripheral area that surrounds the pixel area. The pixel array is disposed in the pixel area. The first power voltage wiring is disposed in the peripheral area and includes a first lower power voltage line and a first upper power voltage line. The first upper power voltage line is disposed on the first lower power voltage line and contacts the first lower power voltage line. The second power voltage wiring is disposed in the peripheral area and includes a second lower power voltage line and a second upper power voltage line. The second upper power voltage line is disposed on the second lower power voltage line and contacts the second lower power voltage line. The first upper power voltage line overlaps the second lower power voltage line in a plan view.

Abstract: A display device includes a substrate including a first area, a second area, and a bending area. A plurality of first wires are positioned in the first area. A plurality of second wires are positioned in the second area. An insulating layer is positioned in the bending area. A plurality of connecting wires are disposed on the insulating layer. Each of the connecting wires is connected with at least one of the first wires and at least one of the second wires. Each of the connecting wires includes a first portion and a second portion alternatingly arranged along an extending direction of the connecting wires. A width of the first portion is wider than a width of the second portion in a direction perpendicular to the extending direction each of the connecting wires.
