The electrical resistivity of pure trans-stilbene nematic liquid crystalline materials is altered by exposure to ultraviolet radiation. These stilbenes can therefore be made to dynamically scatter uniformly or in imagewise configuration and can be added to liquid crystalline compositions to alter the compositions' resistivities.
