Abstract: The embodiments relate to a polyamide-based film that is excellent in solvent resistance and optical properties, to a process for preparing the same, and to a cover window and a display device comprising the same. The polyamide-based film comprises a polyamide-based polymer, wherein when the 3D surface roughness of a first side of the film is measured, the volume (natural volume) between the surface and a reference plane placed at the elevation of the highest peak parallel to the surface plane is 100 μm3 to 2,800 μm3.
