Polyamide film, its manufacturing method, and the cover window used for display devices incorporating it.

Abstract

The invention relates to a polyamide film of excellent solvent resistance and optical properties, a process for its fabrication, and a cover window and display device incorporating it. The polyamide film is made of a polymer based on polyamide, such that when the 3D surface roughness of the first face of the film is measured, the volume (natural volume) between this surface and a reference plane at the height of the highest peak parallel to the surface plane is between 100 µm³ and 2800 µm³.
