| description | To provide a liquid crystal composition for a smart window that operates autonomously, using solely solar light as an energy source, without using electric energy, and a liquid crystal light control element including the same.SOLUTION: A liquid crystal composition according to an embodiment includes: a non-polymerizable liquid crystal compound (LB) that shows a smectic A phase at room temperature and a chiral nematic phase at temperatures higher than the smectic A phase; and a dye including at least one photoisomer group.SELECTED DRAWING: Figure 1
【課題】本実施形態によれば、本実施形態の課題は、電気エネルギーを使用することなく、太陽光のみをエネルギー源とし，自律的に駆動するスマートウィンドウ用液晶組成物、それを備える液晶調光素子を提供することができる。【解決手段】本実施形態の液晶組成物は、室温でスメクチックＡ相を示し、かつ当該スメクチックＡ相よりも高温側でキラルネマチック相を示す非重合性液晶化合物（ＬＢ）と、少なくとも１種の光異性基を有する色素とを含有する。【選択図】図１ |
