Isotropic (the prefix iso indicates equal) reters to the degree of disorder in an ordinary liquid, while anisotropic (the prefix aniso indicates unequal) describes the degree of disorder in liquid crystals. The specific molecular arrangement in a liquid crystal can be described as nematic, cholesteric, or smectic. Liquids Liquid crystals Isotropic Anisotropic Nematic Cholesteric Smectic Liquid crystals have many applications, including computer displays, forehead thermometers, and even mood rings.

The answers are-
Liquid crystals are anisotropic their properties depend on the direction in which they are viewed. Hence liquid crystals are not disordered like the liquid because the molecules have some degree of alignment. Molecules that form liquid crystals tend to be rigid molecules with polar groups that exhibit relatively strong dipole–dipole or dipole–induced dipole interactions, hydrogen bonds, or some combination of both.
