Liquid crystal display including dopant phase-separated from liquid crystal

A method of manufacturing a liquid crystal device which includes a cell comprising a layer of liquid crystal material contained between two substrates, the method comprising the steps of:

• (a) adding to the liquid crystal material under predetermined applied conditions a dopant which is miscible with the liquid crystal material under said conditions;
• and
• (b) changing the temperature of the liquid crystal material so as to cause separation of the dopant out of the liquid crystal material in order to provide a plurality of nucleation points for controlling domain formation within the liquid crystal material.
