Abstract: Devices and methods related to an electrically switchable light controlling device are provided. A device comprises two transparent conductive substrates (10), two inhomogeneous alignment layers (20), each coated on a respective transparent substrate (10), a spacer (30) in between the two transparent substrates (10), a liquid crystal layer in between the two transparent substrates (10); and a polymer network (40) inside the liquid crystal layer. The device can be used for smart windows, touch screen, or privacy windows.
