When we heat some solids, they don't pass into liquid state directly. Rather they form a mesomorphic phase called liquid crystals.Now when we heat liquid crystal, they are converted into pure liquids. But liquid crystal are said to be thermodynamically stable. I am not able to interpret it. What it means to be thermodynamically stable state ? And also how are they used in liquid crystal display?

    $\begingroup$ Thermodynamically stable means that the phase corresponds to a global free energy minimum. $\endgroup$ – lemon Apr 14 '17 at 11:11
