Abstract
An image projection device is provided with at least one laser light source device and uses a light beam exited from the laser light source device as projection light. A laser light source device is provided with a plurality of light source units from which laser beams exit, the plurality of light source units are divided into a plurality of laser light source groups based on magnitudes of angles at which optical axes of the laser beams are incident on the incident surface. As the incident angles of the laser beams from the laser light source group are larger, an average value of convergence angle and/or divergence angle of the laser beams in the laser light source group becomes smaller when the laser beams are incident on the incident surface.
