Abstract: A backplate having a folding region and an unfolding region adjacent to the folding region includes: first and second material layers corresponding to the folding and unfolding regions; and a third material layer between the first and second material layers, the third material layer is more rigid than the first and second materials layers, wherein the first and second material layers extend from the folding region to the unfolding regions such that a thickness of the first and second material layers is gradually reduced from the folding region to the unfolding region.

Abstract: A foldable display device includes a display panel including a first surface and a second surface opposite to the first surface; and an impact absorption film adjacent to the second surface of the display panel and including first and second impact absorption layers. The second impact absorption layer includes a soft part corresponding to a first region of the second impact absorption layer and a hard part corresponding to a second region of the second impact absorption layer. The first impact absorption layer and the soft part of the second impact absorption layer have an elastic modulus value less than an elastic modulus value of the hard part.
