First, it protects the folded circumferential surface and outfolding circumferential surface which are folded and unfolded from the outside, thereby preventing damage such as scratches, stamping and contamination.

Second, since the portion protecting the folding circular surface and the portion protecting the out-folding circular surface are applied so as not to interfere with each other, the user does not have to worry about the spreading order or folding order.

Third, folding occurs in the falling state of the shaft end portion. Shaft end cover shape that blocks the direct contact of the end portion of the shaft and absorbs the shock is applied in a state in which no folding occurs. So that shock absorption is possible without damaging the folding function.

Fourth, since the normally exposed surface related to outfolding is protected by the rotating cover provided with the information window, it is possible to prevent the scratching, staining and contamination of the normally exposed surface related to the outfolding without deteriorating the information checking ability.

Fifth, the in-fold folding side of the in-and-out foldable image display apparatus is kept in the same plane as the folding folded side and the folding support side of the out folding folded side, thereby enhancing the stability in the flat opened state.
