Abstract
An illumination apparatus includes a fluorescence unit, laser light irradiation means, and a beam integration unit. The fluorescence unit has a plurality of phosphors, in which the colors of fluorescence generated due to excitation differ, arranged in different regions. The laser light irradiation means irradiates laser light onto the regions of each color of the fluorescence unit while changing the position at which the laser light strikes the fluorescence unit. The beam integration unit integrates fluorescence from each region of the fluorescence unit on a display panel.
