Provided are a light control film whereby flickering is hard to recognize when observing external light via the light control film, a light control member comprising same, a vehicle, and an electricity supply method for the light control film. In the vehicle, the light control filmhaving a vertically-aligned liquid crystal layer is attached to a sunroof. The light control filmis attached to the sunroofof the vehiclesuch that the liquid crystal molecules fall to the rear of the vehiclewhen an electric field is applied to the liquid crystal layer. As a result, passengers in the vehicle do not sense any flickering inside the car and have no discomfort.
