in turn, a first electrode, an insulating layer, a photo~-
conductive layer, a layer of liquid crystalline composition
and a second electrode (as disclosed in U.S. Patent
3,944,332) is exposed to white light from the liquid crystal
side of the device during exposure of the photoconductive

layer to actinic radiation from the insulating layer side

of the device,
