In a dimming device, in a case where an AC voltage having a first frequency and an amplitude equal to or greater than a first amplitude is applied, the transmittance of light in the first wavelength range is higher than that in a case where a flake is oriented in a direction shielding the light, and in a case where an AC voltage having a second frequency and an amplitude equal to or greater than a second amplitude is applied, the transmittance of light in the second wavelength range is higher than that in a case where a flake is oriented in a direction shielding the light. Here, the second amplitude is equal to or greater than the first amplitude.
