A support device having multiple degrees of freedom includes a base unit, a first support unit, a second support unit and a hinge unit. The base unit includes a base body. The first support unit includes a first support structure disposed on the base body. The second support unit includes a second support structure disposed between the first support structure and at least one display. The hinge unit includes a first hinge structure connected between the first support structure and a first end of the second support structure and a second hinge structure connected between a second end of the second support structure and the at least one display. Therefore, the second support structure can be pivotally disposed on the first support structure through the first hinge structure, and the at least one display can be pivotally disposed on the second support structure through the second hinge structure.
