Abstract: A foldable display includes a housing unit including a hinge member, and a first housing and a second housing coupled via the hinge member, and a flexible display panel including a flexible display layer and a support substrate. The support substrate includes a third portion between a first portion and a second portion of the support substrate. The third portion of the support substrate includes, in a first state, a first region overlapping a at least one step portion and a second region overlapping a planar portion. A first ratio of volume of openings of an opening group in the first region to volume of the first region in the first region of the support substrate is lower than a second ratio of volume of openings of an opening group in the second region to volume of the second region in the second region of the support substrate.
