Abstract: An electronic device includes a display, and a hinge assembly foldable together with the display and corresponding to a folding area of the display. The hinge assembly includes a hinge bracket defining first and second hinge axes, first and second rotators connected to the hinge bracket and respectively rotatable about the first and second hinge axes, first and second sliders connected to the hinge bracket, respectively slidable relative to the hinge bracket in a direction parallel with the hinge axes, and spaced apart from each other in the direction, and an elastic member between the first and second sliders and providing an elastic force in the direction. The first and second rotators respectively include first and second helical structures having a helical shape with the first and second hinge axes as a center, and are each connected to the first and second sliders through the first and second helical structures.
