A projector includes: first and second light blocking members adapted to partially block a light beam from a light source, and a drive section adapted to make the first and second light blocking members perform an opening and closing operation. When the corresponding first and second light blocking members are located at a maximum blocking state, with respect to an opening and closing direction of the first and second light blocking members perpendicular to a system optical axis, a first and second support sections support the first and second light blocking members at predetermined positions on the system optical axis side from intermediate positions corresponding to midpoints of areas between edge portions of the first and second light blocking members on the system optical axis side and parts, to which outer edges of the light beam to be blocked are input.
