る。The properties required of the liquid crystal material used in these liquid crystal displays slightly vary depending on the display system, but the liquid crystal temperature range is wide, and the liquid crystal material is stable against moisture, air, light, heat, an electric field, and the like. This is commonly required in any of the display methods. Furthermore, it is desired that the liquid crystal material has a low viscosity and provides a short addressing time, a low threshold voltage and a high contrast in the cell.

However, as the selection range of the components has been expanded, liquid crystal compositions other than the silacyclohexane compound have been filed. There is an increasing demand for compounds that can be used as ingredients.

原因の一つとなっていた。The liquid crystal compound having a cyclohexane ring or a silacyclohexane ring has two stereoisomers of a cis isomer and a trans isomer with respect to the configuration of substituents on the ring. Of these, only the trans isomer exhibits liquid crystallinity, and if the produced compound is a mixture of cis isomer and trans isomer, the trans isomer must be separated and purified to a high purity, which makes the liquid crystal compound expensive.

のである。As described above, the silaspiro compound of the present invention is more stable than the silacyclohexane compound and is a good component of a liquid crystal composition. In addition, the silaspiro compound of the present invention does not form cis and trans stereoisomers unlike existing liquid crystal compounds, and has only one configuration that exhibits liquid crystallinity, so that the cost of existing liquid crystal compound production is low. This eliminates the need for the trans-isolation and purification operation, which was one of the main factors contributing to the increase in cost, thus increasing economic superiority.
