Abstract: A foldable display apparatus includes: a display panel; first and second set housings arranged in a first direction and supporting the display panel; and a hinge assembly disposed between and connected to the first and second set housings. The hinge assembly is configured to: rotate the first and second set housings inward to in-fold the display panel so that the display panel is disposed between the first set housing and the second set housing; rotate the first and second set housings outward to out-fold the display panel so that the first set housing and the second set housing are disposed between the out-folded display panel; and position the first and second set housings flat to unfold the display panel so that the display panel is flat on the first set housing, the second set housing, and the hinge assembly.

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.
