1. A display apparatus comprising:
a substrate having an outer surface and an inner surface opposite to the outer surface and comprising a bent area between a first area and a second area, the bent area being bent around a bending axis so that the inner surface of the substrate in the first area and the inner surface of the substrate in the second area at least partially face each other, and each of the first area and the second area being planar;
a display unit over the outer surface of the substrate in the first area;
a lower protective film under the inner surface of the substrate in at least a part of the first area;
an adhesive layer between the lower protective film and the inner surface of the substrate in the first area in a vertical direction normal to the outer surface of the substrate in the first area; and
a support layer between the lower protective film in the first area and the inner surface of the substrate in the second area,
wherein, in an area overlapping the first area in a plan view, a total thickness of the support layer in a thickness direction of the display apparatus is greater than a total thickness of the lower protective film in the thickness direction of the display apparatus.
