Frank's free energy density is important in the study of this type of substance, as it helps describe elastic properties and distortions. One model to describe a type of it considers rods oriented in parallel and off-parallel, and predicts that the off parallel state is more probable because repulsion between the hard rods occurs. A small electric field applied to types of this can trigger a shift from a twisted helical configuration in the TN effect. The aforementioned model by Onsager describes a rod shaped type of this substance that also has thread-like defects called disclinations. It was first discovered in derivatives of (*) cholesterol, which gives its name to the cholesteric phase of this. The lower temperature smectic form is ordered positionally in contrast to the more commonly studied nematic phase. For 10 points, name this type of substance between a solid and a liquid that are used in many monitors and televisions.
