Liquid Crystal Display. A display that consists of two polarising transparent panels and a liquid crystal surface sandwiched in between. Voltage is applied to certain areas, causing the crystal to turn dark. A light source behind the panel transmits through transparent crystals and is mostly blocked by dark crystals.
Among its major features are its lightweight construction, its portability, and its ability to be produced in much larger screen sizes than are practical for the construction of CRT display technology. Its low electrical power consumption enables it to be used in battery-powered electronic equipment such as watches and clocks.
