发明名称 プロジェクター
摘要 A projector includes: a light source which emits laser light; a first diffusing section which diffuses the laser light emitted from the light source to emit a first diffused light; and a light modulation device which modulates the first diffused light emitted from the first diffusing section. The light modulation device includes a second diffusing section which diffuses the first diffused light emitted from the first diffusing section to emit a second diffused light, and diffusion intensity distribution of the second diffused light emitted from the second diffusing section is distribution which is consecutive around a central axis of the second diffused light.
