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. The elastic axis members are deformed as the rear hinge covers make a relative movement by bending of the hinge.
