Abstract: A polarizing control film for two-dimensional (2D) display mode/three-dimensional (3D) display mode conversion in a stereoscopic display device, can include a film substrate, a plurality of first and second electrodes alternately arranged on the film substrate, and a liquid crystal layer disposed on the film substrate having the first and second electrodes, the liquid crystal layer being filled with nano liquid crystals exhibiting optical isotropy when no voltages are applied to the first and second electrodes and optical anisotropy when voltages are applied to the first and second electrodes.
