Abstract:
Provided is a foldable display device. The display device comprises a display panel including a folding area and non-folding areas on both sides of the folding area, a back plate disposed under the display panel, a first support layer disposed under the back plate and having an opening pattern in a portion thereof corresponding to the folding area, and an impact absorbing layer disposed under the first support layer. The impact absorbing layer includes a first portion corresponding to the folding area and a second portion corresponding to the non-folding areas, and a modulus of the first portion is greater than a modulus of the second portion. Accordingly, even when a point impact is applied to the folding area, the point impact is converted into a surface impact, so that damage to the display panel or the touch panel by the point impact can be prevented more effectively. Consequently, impact resistance characteristics of the display device may be improved.
