What is the LC in a LCD?

Every article I literally just refers to it as "Liquid Crystal," but what type of crystal, how is it made into a liquid?

Liquid crystals are neither fully liquid nor fully crystalline. It's an in-between state, and the liquid crystals can often (depending on what kind of liquid crystal it is) flow like a liquid, while the molecules still tend to line up in a crystal structure.

The liquid crystals in industrial applications tend to be based on rod-shaped organic molecules that exhibit mutual attraction. So they line up next to each other in a crystal-like manner while still being able to flow.

Biphenyls and triphenyls are commonly used compounds, but there are endless examples. Cell membranes in biology are also liquid crystals.
