In at least one embodiment of the disclosure, a light control device includes a light blocking module to block a luminous flux passing through the light control device in a direction parallel to a system optical axis. The light blocking module includes a first and a second light blocking member. The first light blocking member includes a cutout portion at an end near a system optical axis, the first light blocking member configured so as to change a size of an area blocking the luminous flux in accordance with an opening and closing operation of the light blocking module. The second light blocking member is disposed in proximity to the first light blocking member and configured so as to increasingly block the luminous flux from passing through the cutout portion of the first light blocking member in accordance with the closing operation of the light blocking module.
