An electronic device includes first and second bodies. The second body includes a display module and a supporting assembly. The supporting assembly includes a sliding component slidably disposed on the display module and a pivot component pivoted to the first body and the sliding component. When the second body expands from the first body through the rotation of the pivot component relative to the first body, the sliding component and the pivot component are adapted to rotate relative to each other so that a bottom side of the display module moves to a predetermined position on the first body. When the bottom side is located at the predetermined position, the sliding component and the display module are adapted to slide relative to each other so that the display module rotate around the bottom side, so as to change an included angle between the display module and the first body.
