LCD is a flat panel display technology. The liquid crystals are made of complex molecules. They change their state from solid to liquid. This change depends on the temperature to which they are exposed. In the liquid state, the molecules move around and form a line in a specific direction.

It allows them to reflect light. Crystals are arranged in a matrix with a group of three colors. The colors of these three crystals are red, green, and blue. These crystals form segments which are called pixels. The group of pixels can form numbers, letters or any other shapes arranged in columns and rows.
