1. A display apparatus comprising:
a flexible first layer comprising a bending area;
an adhesive layer on an upper surface of the flexible first layer; and
a second layer attached to the flexible first layer by the adhesive layer,
wherein the flexible first layer is bendable toward a lower surface of the flexible first layer that is opposite the upper surface from a flat state to a first bent state and is further bendable toward the lower surface from the first bent state to a second bent state, and
wherein, when the flexible first layer is in the flat state, a direction of internal stress at a first portion of the flexible first layer is opposite a direction of internal stress at a second portion of the flexible first layer and is opposite a direction of internal stress at the first portion of the flexible first layer when the flexible first layer is in the second bent state.
