    Abstract: The present disclosure provides flexible display device and a support device thereof. The support device includes a skeleton chain which includes a plurality of connected skeleton units. Each skeleton unit includes a head portion and a tail portion joined to the head portion. The head portion has a first rotary surface. The first rotary surface is a cylindrical curved surface or a spherical surface. The tail portion includes a cavity which has a second rotary surface. A radius of the first rotary surface is larger than that of the second rotary surface of the adjacent skeleton unit. The second rotary surface enwraps a part of the first rotary surface of the adjacent skeleton unit such that the head portion of the adjacent skeleton unit engages with the cavity of the tail portion and is rotatable with respect to the cavity of the tail portion.
