Abstract: The present disclosure relates to a foldable display device, including: first and second housings, which are hinged through a first shaft and have first and second closed surfaces respectively and which are capable of rotating about the first shaft to be open or closed; and a touch screen covering the first and second closed surfaces. The touch screen has a bendable region corresponding to a connection region for the first and second housings, the bendable region presenting a planar structure when the first and second housings are open and presenting a smooth curved structure when the first and second housings are closed. A first groove is defined in an end of the first housing neighboring the second housing, and a second groove is defined in an end of the second housing neighboring the first housing. The first and second grooves together define an accommodation space for accommodating the bendable region.
