A bistable switchable liquid crystal device is provided in which the device can be switched between a transparent and an opaque state by a predetermined voltage pulse. The device is based on polymer stabilized cholesteric materials. No additional amount of voltage has to be applied to the device in order to sustain the optical states. Therefore, the device is energy-saving.
