What property of liquid crystals is used in electronics?

The dependence of the properties of a substance on the direction of orientation of molecules causes anisogropy. This property of liquid crystals has wide practical application. For example, compressed to one atmosphere (10 Pa), the layers of liquid crystal molecules are transparent. When the pressure is released, it becomes dull and retains this condition. This effect is used in automatic devices.
