LCD is Liquid Crystal Display, consisting of a thin liquid-crystal gel between two glass panels. Separated into pixels by a grid of wires, each pixel shifts 90 degrees to face one panel or the other. Which panel the pixel faces determines if light goes through and thus manipulates how the image appears.
