1. A display device comprising:
a display module comprising a display panel including a first display area, a second display area and a third display area, a first folding display area which is between the first display area and the second display area and at which the display module is out-foldable, and a second folding display area which is between the second display area and the third display area and at which the display module is in-foldable; and
an impact resistance layer facing the display module, the impact resistance layer comprising:
a first portion corresponding to the first display area of the display module and having an elastic modulus,
a second portion corresponding to the third display area of the display module and having an elastic modulus,
the second portion spaced apart from the first portion in a first direction along the display module, to define a gap between the first portion and the second portion at which the display module is exposed to outside the impact resistance layer, and
the gap which exposes the display module to outside the impact resistance layer spaced apart from each of the first folding display area and the second folding display area along the first direction of the display module,
wherein
the elastic modulus of the first portion is greater than the elastic modulus of the second portion, and
the display module which is both out-folded at the first folding display area and in-folded at the second folding display area disposes:
the first display area and the second display area facing in opposite directions,
the second display area and the third display area facing each other, and
the first display area, the first portion of the impact resistance layer, the second display area, the third display area and the second portion of the impact resistance layer in order.
