liquid crystal
Ordered flowing matter
Liquid crystal is a substance that flows like a liquid but has molecules arranged in orderly patterns like a crystal.
This intermediate state between solid and liquid allows the material to change optical properties when exposed to electric fields—the basis for LCD (liquid crystal display) screens in televisions, monitors, and phones.
