	Liquid crystalline materials have optical properties that are intermediate between perfectly ordered crystals and completely unordered liquids. The molecules involved are able to refract light differently depending on their orientation. This can be changed by magnetism, by an electrical field, or by changing temperature. In this introduction to liquid cyrstals we will apply ideas including index of refraction, polarizability, crystal lattices and intermolecular forces.

	Liquid crystals are widely used for electronic displays and TVs. In these devices an array electrically controlled LC pixels are placed in front of colored light sources or reflect light ~~differentialy~~ as in a calculator. An LC filter can also be used to modulate a projected light source as in an LCD projector. Liquid crystal paint can be used to indicated temperature and pressure which can then be analyzed optically.		Liquid crystals are widely used for electronic displays and TVs.
