Abstract: Embodiments relate to a polyamide-based film, a manufacturing method therefor, and a cover window and a display device each comprising same, wherein the polyamide-based film has excellent optical characteristics, such as transmittance, haze, and yellowness, and excellent mechanical characteristics, such as modulus and thickness uniformity. The polyamide-based film contains a polyamide-based polymer and includes a sum XRD peak obtained by adding up a first XRD peak having the maximum value in the section where the 2θ value is 10° (inclusive) to 20° (exclusive) and a second XRD peak having the maximum value in the section where the 2θ value is 20° to 25°, on the XRD graph, wherein the full width at half maximum of the first XRD peak is 6° or less.
