A liquid crystal light control element, a lens barrel, and an imaging device, which are so designed as to adequately control the amount of light led to the imaging element at the time of photographing in a bright ambience are provided. The lens barrel includes an optical system, a liquid crystal light control element, and an imaging element. The object image captured by the optical system reaches the imaging element through the liquid crystal light control element, which is composed of a first liquid crystal light control unit, a second liquid crystal light control unit, and a first and a second liquid crystal layers, which are placed on top of the other in their thickness direction.
