Display apparatus having reduced defects

A display apparatus comprising:

• a substrate comprising a first area including a display area, a second area spaced apart from the first area, and a bent area between the first area and the second area and connecting the first area and the second area to each other, wherein the substrate is bent about a bending axis;
• an inorganic insulating layer over the substrate and directly contacting an upper surface of the substrate, wherein the inorganic insulating layer comprises a first opening or a first groove formed to overlap the bent area when viewed in a direction perpendicular to the substrate in the bent area and extending along a first direction, and a second opening or a second groove located outside the display area, a part of the second opening or the second groove extending along a second direction different from the first direction along at least a part of the display area;
• and
• an organic material layer, wherein the organic material layer at least partially fills the first opening or the first groove, and at least partially fills the second opening or the second groove.
