Abstract
Embodiments relate to a polyamide-based film that is colorless and transparent, is excellent in mechanical properties and optical properties, has a wide angle of view by securing at least a certain level of luminance at various angles, and, in particular, has gloss characteristics similar to those of glass, a process for preparing the same, and a cover window comprising the same. The polyamide-based film comprises a polyamide-based polymer, wherein when the polyamide-based film is placed on a surface light source, light is irradiated from the surface light source, and the luminance value (L) measured in the normal direction of the surface light source is 100%, the luminance value (L) measured in the direction of 50° from the normal direction of the surface light source is 25% or more.
