Abstract
This projector includes a laser light generation portion, a projection portion scanning laser light, and a projection screen. The projection screen includes a lens member including a plurality of lens portions splitting the laser light and a diffusion member arranged to be opposed to the lens member, having an incident surface and a diffusion portion. The diffusion portion of the diffusion member is arranged at a position apart by a distance larger than the focal length of the lens member along an optical axis with respect to the optical principal surface of the lens member.
