Abstract:
Provided is a stereoscopic surface display device including a stereoscopic display unit having a cell area, wherein the stereoscopic display unit includes a first flexible layer, a first optical waveguide and a first optical output unit in the first flexible layer, wherein the first optical output unit are disposed in the cell area, a first light source disposed on a side of the stereoscopic display unit, wherein the first optical waveguide connects the first light source and the first optical output unit, a first photothermal response layer on the first flexible layer, wherein the first photothermal response layer is 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.
