Title: LIGHT CONTROL FILM, LIGHT CONTROL SYSTEM, AND LIGHT CONTROL MEMBER
Abstract:
Provided are a light control film and a light control system, which not only simply change the amount of transmitted light but also can be used for a wider range of applications. This light control film 1 includes a first electrode 11, a second electrode 16, a liquid crystal material, and a dichroic dye, and has a guest-host type liquid crystal layer 8 in which light transmittance varies with the potential difference between the first electrode 11 and the second electrode 16, wherein the liquid crystal layer 8 has a first haze value when the potential difference is a first potential difference, has a second haze value when the potential difference is a second potential difference, and has a third haze value higher than at least the second haze value when the potential difference is a third potential difference between the first potential difference and the second potential difference.
