The polyester film according to the embodiment achieves the elasticity required for a cover of a flexible display by increasing the rate of increase in stress in an initial stage of strain to a certain level or higher. As a result, it is possible to maintain the original characteristics when it is applied to a cover of a flexible display device and subjected to a plurality of repeated folding. Accordingly, the polyester film can be applied to a cover of a flexible display device, in particular, a foldable display device to exhibit excellent characteristics.

An adhesive composition includes a resin, a crosslinking agent, and a light absorber. The light absorber includes at least one selected from the group consisting of a benzophenone-based compound, a cyanoacrylate-based compound having a ring structure, a benzotriazole-based compound, and a sterically hindered amine compound having a ring structure.

In the polyester film according to an embodiment, the strain with respect to tensile load and the crystallinity are adjusted to specific ranges, whereby it is possible to achieve the flexibility that does not cause deformation even when a certain load is sustained for a long period of time and the resistant characteristics to the impact of external pressing. Accordingly, the polyester film can be applied to a cover of a flexible display device, in particular, a foldable display device to exhibit excellent characteristics.

A window includes a base layer including a folding region in which a groove is defined and a non-folding region, and a resin disposed on the groove and including a thiol group, wherein a difference between the refractive index of the base layer and the refractive index of the resin is less than about 0.1.
