Abstract
The embodiments relate to a polyester film, and a laminate and a foldable display device comprising the same. As the polyester film has a yield elongation in a specific range, it can be excellent in folding characteristics, along with high surface hardness.
Claims13
A polyester film, wherein when a first direction and a second direction perpendicular to each other are defined in the plane of the film, the yield elongation in at least one direction of the first direction and the second direction is 2.2 to 2.6%, and the thickness is 80 to 150 μm.
A laminate, which comprises a transparent substrate;
- and a polyester film disposed on the transparent substrate,
- wherein when a first direction and a second direction perpendicular to each other are defined in the plane of the polyester film, the yield elongation in at least one direction of the first direction and the second direction is 2.2 to 2.6%, and the thickness of the film is 80 to 150 μm.
A foldable display device, which comprises a foldable display panel;
- a transparent substrate disposed on the foldable display panel;
- and a polyester film disposed on the transparent substrate,
- wherein when a first direction and a second direction perpendicular to each other are defined in the plane of the polyester film, the yield elongation in at least one direction of the first direction and the second direction is 2.2 to 2.6%, and the thickness of the film is 80 to 150 μm.
