Zusammenfassung:	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 includes a first electrode, a second electrode, a liquid crystal material, and a dichroic dye, and has a guest-host type liquid crystal layer in which light transmittance varies with the potential difference between the first electrode and the second electrode, wherein the liquid crystal layer 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.
