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.

Abstract: A display apparatus includes a substrate. A display unit is disposed on the substrate and includes a display region and a non-display region. At least one light-emitting device is disposed in the display region. First and second power supply lines, configured to supply driving power to the at least one light-emitting device, and a pad unit, are disposed in the non-display region. The first power supply line includes a first fan-out wire portion electrically connected to the pad unit, and a first extension portion electrically connected to the first fan-out wire portion. The second power supply line includes a second fan-out wire portion electrically connected to the pad unit, and a second extension portion electrically connected to the second fan-out wire portion. The first extension portion has a width W1 and the second extension portion has a width W2. The width W1 is greater than the width W2.
