A water ionizer includes a stacked electrolyzer and a flow switching device, with an inlet being separate from an outlet. Water entering an input regulator is distributed at a predetermined ratio before being supplied to an electrolyzer module to minimize acidic water to be discarded. Water supplied from the input regulator is directed to pass through the electrolyzer module in a crossing manner to delay flows of water to improve the efficiency of electrolysis. Electrolyzer cells are stacked on and fitted to each other to simplify an assembly process and improve convenience. Electrode plates of the electrolyzer module are fixedly fitted into a frame to facilitate an assembly process and improve a fabrication process. The input regulator and a flow switching output unit are connected via a connecting shaft to synchronize the operations thereof to obtain reliability.

A vertical alignment liquid crystalline compound containing a laterally substituted aromatic cyclic moiety. The liquid crystalline compound has a wide temperature range of the nematic phase, a high optical anisotropy and a high negative dielectric anisotropy. In addition, since the rotation viscosity and the K33/K11 ratio of the liquid crystalline compound are maintained at a low level, the liquid crystalline compound can be effectively used as a liquid crystalline medium having good image quality and a high response speed even when applied to thin liquid crystalline cells.
