Abstract
Disclosed is a hinge module including a hinge structure having a first sub-hinge structure including a first center bracket and a first hinge bracket that rotates through a specified angle in a first direction and a second sub-hinge structure including a second center bracket and a second hinge bracket that rotates through a specified angle in an opposite direction to the first direction. The first hinge bracket and the second hinge bracket are separated from each other and are disposed between the first center bracket and the second center bracket, and hinge motion of the first sub-hinge structure is performed independently of hinge motion of the second sub-hinge structure. The hinge module and a foldable display device including the hinge module suppress a phenomenon in which the hinge module is opened when the housing structures are twisted, thereby preventing damage to the foldable display device.
