Abstract: An electronic device includes a foldable housing that includes a first hinge structure; a second hinge structure; a first housing structure including a first surface, a second surface facing away from the first surface, and a first side member surrounding a first space between the first surface and the second surface; a second housing structure including a third surface, a fourth surface facing away from the third surface, and a second side member surrounding a second space between the third surface and the fourth surface; a third housing structure including a fifth surface, a sixth surface facing away from the fifth surface, and a third side member surrounding a third space between the fifth surface and the sixth surface, wherein the first housing structure and the second housing structure are connected through the first hinge structure and the third housing structure are connected to the second housing structure through the second hinge structure, wherein through the first hinge structure, the second surfac

Abstract: Embodiments of the present disclosure provide a foldable display device comprising both an outwardly folding structure and an inwardly folding structure. Size differences generated in an outwardly folding process and an inwardly folding process can be compensated for each other by designing folding sizes of the structures, thereby achieving the purpose of matching the size of a mechanism and a display panel during folding process of the foldable display device.
