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.
