LCD is Liquid Crystal Display and LED is Light emitting diode.
If you are talking about the brand of drink, Crystal Light is a solid (as a powder), and a liquid (when it is dissolved into water to make the drink). If you are talking about light reflecting from a crystal, light is energy, not matter.

Some advantages of a liquid-crystal display are that it is light, compact, has no geometric distortion, used minimal power, thin, has little flicker, and more.
Liquid Crystal Display is made up of many liquid crystals, the liquid crystals themselves do not emit light, but the brightness of the monitor or screen is set by using a back light using either fluorescent lighting or LED lighting
LCD (liquid crystal display)
DLP is digital light processing and LCD is liquid crystal display.
A LCD (liquid crystal display) monitor with a LED (light-emitting diode) backlight
light passes through transparent, and reflects off opaque.
The term "liquid crystal diode" was invented by patent lawyers in late 1970's for the emerging liquid crystal display technology to rhyme with the then dominant light emitting diode display technology. The term is misleading as the liquid crystal cell is not a diode in the ordinary meaning of the word. Since then the incorrect term has been adopted to patents (over 600 patents describing liquid crystal cells as diodes) and scientific literature in addition to its misuse in lay-articles in internet.
The iPad is a liquid crystal display backlit with light emitting diodes.
LCD is liquid crystal display, used in computer monitors and handheld devices; LED is a light emitting diode, and are used in some TV's and devices. LED's are the small, bright lights, like a camera or phone flashlight.
