Abstract:
A projector includes an image formation apparatus that forms an image, a lens barrel that accommodates a projection lens that projects the formed image, and a light blocking portion that is configured as a member separate from the lens barrel, is located in a position between the image formation apparatus and the lens barrel, and blocks light to be incident on the lens barrel. The configuration of the projector allows blockage of light incident on the lens barrel and hence prevention of distortion of the lens barrel.
