Liquid crystal (LC) is a state of matter with qualities that fall in between liquids and solid crystals.
A liquid crystal, for example, may flow like a liquid but have its molecules arranged in a crystal-like pattern.
Liquid-crystal phases come in a variety of shapes and sizes, each with its own set of optical properties (such as textures).
Domains where liquid-crystal molecules are orientated in opposite orientations correspond to the contrasting sections in the textures.
The molecules, on the other hand, are well organized within a domain.
It’s possible that LC materials aren’t always in a liquid-crystal state of matter (just as water may turn into ice or water vapor).
