Abstract: A foldable display apparatus with excellent portability is provided. The display apparatus includes a flexible display panel, which can be folded in a small size. The display apparatus has a tri-fold mechanism, in which a region folded with a first surface itself of the display apparatus facing each other and a region folded with a second surface opposite to the first surface itself facing each other can be formed. Thus, even a display panel which has a relatively high aspect ratio can be folded in a small size by provision of a folding crease in the short-axis direction, so that portability can be improved.
