Abstract: A liquid crystal display of the chiral smectic type is caused to have grey scales, by applying a voltage of an intermediate level to the liquid crystal. Within each picture element of the display, there are a number of domains of the liquid crystal layer, some being transparent while the other being opaque rendering grey tone to the picture element.
