Display apparatus

A display apparatus comprising:

• a substrate comprising a bending area between a first area and a second area;
• an inorganic insulating layer arranged over the substrate, the inorganic insulating layer having an opening or a groove corresponding to the bending area;
• a wiring unit extending to the second area through the bending area, arranged on the inorganic insulating layer, overlapping the opening or the groove;
• and
• an organic material layer between the inorganic insulating layer and the wiring unit, the organic material layer configured to fill the opening or the groove,
• wherein the inorganic insulating layer comprises a first concavo-convex surface and a second concavo-convex surface, the wiring unit comprises a first wire and a second wire that are adjacent to each other, a section of the first wire is between the first concavo-convex surface and the second concavo-convex surface in a lengthwise direction of the first wire, and convex parts or concave parts of at least one of the first concavo-convex surface and the second concavo-convex surface are between the first wire and the second wire, and
• wherein the bending area is disposed between the first concavo-convex surface and the second concavo-convex surface.
