    Abstract: A flexible display apparatus includes a flexible display panel which includes a flexible display substrate having an active area and an inactive area outside the active area. The inactive area which extends from the active layer and includes a bending area foldable or adapted to be folded in a first direction. The bending area includes a deformation unit that includes a plurality of unit deformable portions such that the flexible display panel is foldable or adapted to be folded in a second direction. The flexible display substrate may include an encapsulation layer on the flexible display substrate. The flexible display apparatus may include a functional layer on a side of the flexible display panel. A folded end portion of the flexible display panel may be on the functional layer. The flexible display apparatus may also include a driving unit.
