Abstract: Embodiments relate to a foldable display apparatus including a hinge providing supporting for a bending area of a flexible display panel. The flexible display panel includes a first flat display area and a second flat display area at both sides of a bending display area. A first rear cover provides support for the first flat display area and has a first edge. A second rear cover provides support for the second flat display area and has having a second edge facing the first edge and parallel to the first edge. The hinge includes rear hinge covers longitudinally extending parallel to the first edge and the second edge, and elastic axis members coupling the plurality of rear hinge covers in an interlocking and rotatable manner.

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.
