A waterproof case applied with a waterproof means in the form of a sealed zipper bag has been proposed (Korea Patent Registration: 10-1395885), but when it is applied to a foldable image display device whose circumferential shape changes when switching to a folded or unfolded state, it is converted to a folded and unfolded state. This is not possible, or a zipper bag bursting or unintentional opening problem occurs.

A waterproof case has been proposed (Korea Patent Registration: 10-1165193), which wraps the existing flat-type smartphone that cannot be folded inside and is fixed with the waterproof case component divided into the upper part and the lower part (Korea Patent Registration: 10-1165193), but the shape of the circumference is changed when switching to the folded and unfolded state. It cannot be applied to a foldable video display device.

The technical problem to be achieved by the present invention is as follows.
