Abstract: In a foldable display device, stretchability is given to an outermost area of the folding area of the first support substrate to which a relatively high stress is applied. Thus, the folding radius at the outermost area increases, which relatively reduces the stress at the outermost area. Accordingly, it is possible to suppress occurrence of cracks in the outermost area.
