1. A foldable display, comprising:
a flexible display panel including: an impact absorbing layer including a metal film; and a display layer provided on a surface of the impact absorbing layer;
a first region, a second region, and a third region that are included in a region of the flexible display panel, the third region being positioned between the first region and the second region;
a first support substrate that is inflexible, the first support substrate supporting the first region from toward the impact absorbing layer;
a second support substrate that is inflexible, the second support substrate supporting the second region from toward the impact absorbing layer;
a folding mechanism connected to the first support substrate and the second support substrate, and overlapping with the third region in plan view; and
a slit provided to the metal film at least in a first position at a shortest distance, from the third region, shorter than a shortest distance from an end portion of the first region across from the third region, or in a second position at a shortest distance, from the third region, shorter than a shortest distance from an end portion of the second region across from the third region.
