手性可以说是当今液晶研究中最重要和最复杂的课题。在这些有组织的相对称性的降低导致了各种新的相结构，性质和应用。分子的不对称赋予了液晶相形式手性，表现为相组成分子的螺旋有序的形成。同样，分子的不对称性也会降低空间的对称性，从而导致某些相具有不寻常的非线性特性，如铁电性和热释电性。在下面的文章中，一般地描述了手性在液晶体系中的各种影响。
Chirality has become arguably the most important and complex topic of research in liquid crystals today. The reduced symmetry in these organized phases leads to a variety of novel phase structures, properties, and applications. Molecular asymmetry imparts form chirality to liquid-crystalline phases, which is manifested in the formation of helical ordering of the constituent molecules of phase. Similarly, molecular asymmetry imposes a reduction in the space symmetry, which leads to some phases having unusual non-linear properties, such as ferroelectricity and pyroelectricity. In the following article the various effects of chirality in liquid-crystalline systems are described in general terms.
