Q. Explain Working of Liquid-crystal display?

This display needs only microwatts of power (over a thousand times less than a LED) and is used in such devices as electronic wristwatches.With the application of an electric field the molecules of the liquid-crystal material are straightened out, absorbing the light, and the display appears black. With no electric field applied, the display appears as a silver mirror because the light is reflected.
