Kobayashi研究了交流电场稳定性、聚酰亚胺Langmuir-Blodgett膜对FLC取向的影响以及电荷转移络合物在FLC主体中的掺杂效应。内田描述了铁电陶瓷板上FLC的取向技术，阐明了FLC分子均匀取向的机理，找到了一个合适的参数来评价摩擦表面的取向能力。Onnagawa和Miyashita还试图通过使用几种聚合物薄膜和倾斜蒸发的薄层来实现稳定可靠的分子取向。Komura用X射线衍射研究了近晶层，并注意到了“人字形结构”。考虑到极化电荷的影响，Akahane分析了开关过程。Ishibashi研究了各向异性介电常数对高场区开关特性的影响，并利用新提出的模型分析了开关时间与场的关系。Takazoe和Fukuda阐明了之字形缺陷以及内部错动环的结构。他们还发现，由于极化电荷和人字形结构的存在，极化平行于束缚表面的第三均匀态是稳定的。KAI和Imasaki研究了SX相区翻转过程中的形核过程，认为该过程是高度各向同性的准一维过程。在面向化学的研究领域，人们从微观的角度研究了FLC晶胞的结构和性质。草林系统地合成了几个化合物，并试图阐明Sc*相的出现与分子结构之间的关系。木村发展了一个分子理论，解释了分子长轴在SC相中从正常层倾斜的原因。丸山使用了一种测量高频介电常数的复杂技术，研究了分子长轴的旋转状态。

Kobayashi studied AC electric field stabilization, polyimide Langmuir-Blodgett films for the orientation of FLC, and the doping effects of a charge transfer complex into FLC host. Uchida descibed an alignment technique of FLC on a ferroelectric ceramic plate and clarified the mechanism of homogeneous molecular alignment of FLC, finding a suitable parameter to evaluate the alignment power of the rubbed surface. Onnagawa and Miyashita also tried to realizestable and reliable molecular alignment by using several polymer films and obliquely evaporated thin layers.Komura studied the smectic layer by X ray diffraction and noticed the "chevron structure". Taking account of the effect of polarization charge, Akahane analized the switching process. Ishibashi inverstigated the effect of anisotropicdielectric constant on the switching characteristics in a high field region andanalized the field dependence of switching time in terms of a newly proposed model. Takazoe and Fukuda clarified the structure of zig-zag defects as well internal disclination loops. They also discovered that the third uniform state, where the polsrization is parallel to the bounding surfaces, is stabilized becauseof the polarization charge and the chevron structure. Kai and Imasaki studiedthe nucleation process in domain reversal of the SX phase and concluded that the process is highly amisotropic and quasi one dimensional.In the chemistry oriented fields of research, the structure and properties ofFLC cells has been studied from a microscopic point of view. Kusabayashi systematically synthesized several coumpounds and tried to clarify the relation between the appearance of the SC* phase and the molecular structure. Kimura developed a molecular theory, explaining the reason why the molecular long axis tilts from the layer normal in the SC phase. Maruyama investigated the state of rotation around the molecular long axis by using a sophisticated techniwue in measuring high frequency dielectric constants.
