A hinge includes a bearing plate, a linkage mechanism, a shell element, and an elastic element. The linkage mechanism is linked to the bearing plate. The shell element is disposed on the support, is connected to the linkage mechanism and includes a receiving space. The elastic element is disposed in the receiving space and abuts against between the linkage mechanism and the shell element to provide an elastic force. When an external force is applied, the display device and the bearing plate rotate relative to the support between a first position and a second position. The bearing plate is linked to the linkage mechanism to compress or loosen the elastic element, and then the elastic force is changed. When the external force is removed, the display device and the bearing plate can be stopped at once at any position between the first position and the second position.
