A foldable display apparatus includes a mid-layer having a hinge region; a panel on the mid-layer; a pair of set frames under the mid-layer; and a hinge portion connected to the pair of set frames, and moving as the panel is folded or unfolded. Since a sliding section of the panel in the hinge region is compensated for during the folding and unfolding of the panel, the size of a bezel that would otherwise accommodate a sliding section can be reduced.
