Liquid crystal is a state of matter – like liquid, solid, and gas. The term “liquid crystal” is used to denote a material that exhibits a liquid phase under certain conditions. In order to understand what differentiates a liquid crystal phase from a liquid or solid phase, it is necessary to understand what defines these phases.
