ディスプレイの進化を加速させる重合性液晶材料

抄録

We have investigated optical properties of retardation films with negative wavelength dispersion-birefringence (NWD) prepared by polymerizable liquid crystal materials. New liquid crystalline monomers suitable to a coating have been developed, and have also been optimized to improve optical properties and durability of the retardation film. Solubilities of new monomers were more than 20%wt in MIBK. We succeeded in fabricating retardation films having a homogenous alignment (+A plate) of which retardation ratio was 0.867 (450nm/550nm), and 1.017 (650nm/550nm). Furthermore, we also succeeded in fabricating retardation films having a homeotropic alignment (+C plate) or a hybrid alignment (O plate) with NWD.
