PROBLEM TO BE SOLVED: To solve the problem that the unevenness of surface uniformity in excitation light in a light source device in which excitation light is emitted to a fluorescent body, and fluorescent body emission light is used as light source light may cause the luminance unevenness of surface uniformity in the light flux of outgoing light in fluorescent light emitted from the fluorescent body to be emitted from the light source device as the light source light.SOLUTION: The light source device includes: an excitation light source 71 which emits excitation light; a fluorescent body which emits fluorescent light by receiving the excitation light from the excitation light source 71; a diffusion panel and a condenser lens to which the fluorescent light is made incident; and a driving part which moves a diffusion panel such that the incident position of the fluorescent light on the light incident surface of the diffusion panel fluctuates. |
