Noun
A liquid crystal display (often referred to as LCD) is a thin, flat display device made up of any number of color or monochrome pixels arrayed in front of a light source or reflector. Engineers like it because it uses very small amounts of electric power, and is therefore suitable for use in battery-powered electronic devices.
LCDs are not susceptible to burn-in and are common in gadgets like laptop computers, digital clocks and watches, microwave ovens and CD players.
