1. A display apparatus comprising:
a substrate comprising a bent area between a first area and a second area;
a display unit over a first surface of the substrate at the first area;
a protective film over a second surface of the substrate that is opposite to the first surface, and defining an opening corresponding to the bent area; and
an adhesive layer between the substrate and the protective film, and in the opening,
wherein the protective film comprises:
a first first portion and a second first portion each having a first thickness;
a first second portion and a second second portion each adjacent to a respective side of the opening, and each having a second thickness that decreases in a direction toward the opening; and
a first third portion between the first first portion and the first second portion, and a second third portion between the second first portion and the second second portion each having a third thickness that is greater than the first thickness,
wherein the first third portion and the second third portion are spaced apart from each other when the substrate is bent such that a portion of the substrate in the first area and a portion of the substrate in the second area are parallel to each other.
