Abstract
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.
