摘要： A light control sheet includes a light control layer and two transparent electrodes sandwiching the light control layer. In the light control sheet, absolute values of one or more target change ratios have a maximum value of 0.7 or more, each target change ratio being a change ratio of a light-shielding ratio [%] with respect to an applied voltage [V] in a target range, the target range being a range of the applied voltage in which a light-shielding ratio of the light control sheet changes by 10%, the light-shielding ratio being prescribed by JIS L 1055:2009.
