Abstract: Provided is a foldable display that is excellent in mass production applicability, and that is resistant to image distortion that can appear in the folding portion after the display is repeatedly folded, and also a mobile device equipped with such a foldable display. The foldable display includes a hard coating film on at least part of the front surface thereof, the hard coating film including a polyester film having an intrinsic viscosity of 0.65 to 1.0 dl/g as a substrate film; a hardened layer formed from a polyimide-based resin, the hardened layer having a thickness of 0.5 to 3.0 ?m; and a hard coating layer, wherein the hardened layer and the hard coating layer are present in this order at least on the front surface side of the substrate film.
