본 발명은 폴더블 표시장치에 관한 것으로, 특히 내충격성이 향상된 폴더블 표시장치에 관한것이다. 본 발명의 특징은 각 구성요소의 모듈러스 값을 높고 낮음이 서로 교대로 번갈아 위치하도록 함으로써, 외부로부터 충격이 가해지더라도 터치패널이나 OLED패널로 전달되는 것을 최소화할 수 있으면서도, 백플레이트의 배면으로 충격흡수필름을 더욱 위치시킴으로써, 외부로부터 가해지는 충격에 의해 터치패널이나 OLED패널의 파손이 발생하는 것을 보다 효율적으로 방지할 수 있다. 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.
