Claim 0:
1. A stereoscopic surface display device comprising a stereoscopic display unit having a cell area,
wherein the stereoscopic display unit comprises:
a first flexible layer;
a first optical waveguide and a first optical output unit that are in the first flexible layer, the first optical output unit being disposed in the cell area;
a first light source disposed on a side of the stereoscopic display unit, the first optical waveguide connecting the first light source and the first optical output unit;
a first photothermal response layer on the first flexible layer, the first photothermal response layer being configured to receive output light emitted from the first optical output unit and emit thermal energy; and
a shape deformation layer on the first photothermal response layer,
wherein the shape deformation layer is configured to generate bending deformation by receiving the thermal energy from the first photothermal response layer.
