A dimming member (10) is provided with a first dimming unit (20) and a second dimming unit (40) laminated on the first dimming unit (20). The first dimming unit (20) may adjust the visible light transmittance by applying a voltage. The second dimming unit (40) may adjust the haze value by applying a voltage. The first dimming unit (20) has a first absorption-type polarizing plate (21), a second absorption-type polarizing plate (22), a first liquid crystal cell (30) disposed between the first absorption-type polarizing plate (21) and the second absorption-type polarizing plate (22), and a reflective polarizing plate (23) disposed between the first absorption-type polarizing plate (21) and the first liquid crystal cell (30). The first liquid crystal cell (30) can be switched between a state in which light is transmitted while maintaining the polarization direction and a state in which light is transmitted while changing the polarization direction by applying a voltage.

    调光部件(10)具备第一调光单元(20)和层叠于第一调光单元(20)的第二调光单元(40)。第一调光单元(20)可以通过施加电压而调节可见光透射率。第二调光单元(40)可以通过施加电压而调节雾度值。第一调光单元(20)具有第一吸收型偏振板(21)及第二吸收型偏振板(22)、配置于第一吸收型偏振板(21)及第二吸收型偏振板(22)之间的第一液晶单元(30)、以及配置于第一吸收型偏振板(21)及第一液晶单元(30)之间的反射型偏振板(23)。第一液晶单元(30)可以通过施加电压而切换在维持偏振光方向的状态下使光透射的状态、和改变偏振光方向而使光透射的状态。
