1. A display apparatus comprising:
a substrate comprising a bending area located between a first area and a second area and bent in the bending area;
a display unit arranged over an upper surface of the substrate and located in the first area;
a protection film located over a lower surface of the substrate and comprising a protection film base and a viscous layer, the protection film base not directly contacting the substrate; and
a bending protection layer comprising a first bending protection layer and a second bending protection layer and corresponding to the bending area,
wherein the protection film base has an opening corresponding to the bending area or at least a part of the first area and the second area, wherein the opening extends through an entire thickness of the protection film base,
wherein the first bending protection layer is arranged over at least a part of a boundary of the opening or over an outside of the boundary of the opening, and at least a part of the second bending protection layer is arranged over an inside of the boundary of the opening, and
wherein a height of one point of the first bending protection layer is higher than a height of one point of the second bending protection layer.
