Abstract: A reflective active variable lens includes an upper electrode, a lower electrode disposed in parallel to the upper electrode, a deformation part disposed between the upper electrode and the lower electrode, a reflective part disposed on the upper electrode, and a support part disposed to surround the deformation part. Here, the deformation part and the support part are connected to each other to provide a single structure, the deformation part is expanded from an initial shape when an electric field is formed between the upper electrode and the lower electrode, and the expanded deformation part is contracted when the electric field is removed and restored to the initial shape.
