Abstract: A foldable display device includes a display panel including a folding area and non-folding areas on both sides of the folding area in a folding direction; a first support substrate configured to support the display panel under the display panel and including a plurality of opening patterns corresponding to the folding area; and a second support substrate between the display panel and the first support substrate and including a plurality of protrusion patterns protruding to be inserted into the plurality of opening patterns. Sizes of the plurality of protrusion patterns are smaller than sizes of the corresponding plurality of opening patterns. Therefore, it is possible to improve durability and prevent or at least reduce degradation of folding characteristics of the foldable display device.
