Реферат: A light source device comprising: a light source section (1) which generates any one of blue light, red light, and green light; a phosphor (5) which generates a fluorescence including the two colors other than the color of the light emitted from the light source section (1); a color-changing section (10) which changes one of the two colors of the fluorescence emitted from the phosphor (5) to another color regularly and irradiates it to the image-forming element (13); and a light path-switching section (3) which switches a light path in which a fluorescence excited by the color light emitted from the light source section (1) passes towards the color-changing section (10) and a light path in which the color light emitted from the light source section (1) passes towards the image-forming element (13) regularly.
