Smectic liquid crystals, on the other hand, arrange themselves in layered sheets within different smectic phases, as shown in the figure, the molecules may take on different alignments relative to the plane of the sheets. The molecules of nematic liquid crystals align themselves with their axes in parallel, as shown in the figure. LCDs utilize either nematic or smectic liquid crystals. In common with solid crystals, liquid crystals can exhibit polymorphism i.e., they can take on different structural patterns, each with unique properties. As in solid crystals, however, they arrange themselves in recognizably ordered patterns. As in liquids, the molecules of a liquid crystal can flow past one another. Liquid crystals are materials with a structure that is intermediate between that of liquids and crystalline solids. Electro-optical effects in liquid crystals LCDs are commonly used for portable electronic games, as viewfinders for digital cameras and camcorders, in video projection systems, for electronic billboards, as monitors for computers, and in flat-panel televisions. Liquid crystal display (LCD), electronic display device that operates by applying a varying electric voltage to a layer of liquid crystal, thereby inducing changes in its optical properties.
