PROBLEM TO BE SOLVED: To improve color reproducibility by allowing hue of light projected from an excitation light source to be adjusted to be proper hue.SOLUTION: A light source device includes: an excitation light source that emits excitation light; and a rotation plate 101 capable of being rotationally controlled in which a phosphor portion 101a that converts the excitation light emitted from the excitation light soure into fluorescent light, a first diffusion portion 101b that diffuses the excitation light, and a second diffusion portion 101c in one area of which a fluorescent layer 101d for converting the excitation light into the fluorescent light is disposed and in the other area of which the excitation light is diffused are circumferentially juxtaposed.SELECTED DRAWING: Figure 3 |
