What is positional order in liquid crystals?

What is positional order in liquid crystals? Positional order is the degree to which the position of an average molecule or groups of molecules exhibit translational symmetry. In liquid crystal there are cohesive forces between the molecules that makes them try to orient in one direction. At the same time the temperature is causing entropy in the system.

What is order parameter in liquid crystals? To quantify just how much order is present in a material, an order parameter (S) is defined.
