Abstract
A display apparatus including a repair wiring is provided. The repair wiring may be disposed in each pixel area. A repair connecting area and a repair releasing area which are spaced away from a pixel driving circuit and a lower electrode of a light-emitting device may be defined in each pixel area. The repair wiring of each pixel area may overlap with the repair connecting area and the repair releasing area of the corresponding pixel area. The light-emitting device of each pixel area may be disposed on at least one insulating layer covering the repair wiring of the corresponding pixel area. Thus, in the display apparatus, a generation of a dark spot due to a repair releasing process may be minimized.
