Abstract
The embodiments relate to a polyamide-based film excellent in optical properties, mechanical properties, and processing suitability and to a cover window and a display device comprising the same. The polyamide-based film comprises a polyamide-base polymer, wherein a dipolar solvent compatibility represented by the following equation is 18.5 to 24: Dipolar solvent compatibility=√{square root over ((σ−δ1)+(σ−δ1))}. In the equation, σis a value of a dispersible component in surface energy of the polyamide-based film, σis a value of a polar component in surface energy of the polyamide-based film, δ1is a value of a dispersible component in Hansen solubility parameter of the dipolar solvent, and δ1a value of a dipolar component in Hansen solubility parameter of the dipolar solvent.
