Abstract
The present invention realizes both a laser light source that, despite the use of a plurality of laser diodes and transmission through a modulator that allows transmission of a specific orientation of linearly polarized light, is free from the occurrence of uneven luminance or uneven color, and a projector device that uses this laser light source. The laser light source is provided with a plurality of laser diodes that are mounted on a substrate and that emit linearly polarized light in the same direction. The plurality of laser diodes are arranged such that the orientation of the emitted linearly polarized light is different for each laser diode.
