Liquid crystals are a state of matter that holds properties that are between those of a solid crystal and a liquid state.
UNITED KINGDOM - JULY 08: While the molecules may hold the structure and orientation of a crystal, the substance may still flow and drip like a liquid. They are found abundantly in the natural world as many proteins and cell membranes. But, increasingly, LCs are being used in electronics such as mobile phone and television displays. Using polarized light to highlight the molecular orientation, these micrographs capture the variations of LCs when subjected to changes in temperature or magnetic or electric fields.
