<p>Described is a light source unit which emits fluorescence light to a display element which displays an image by using the fluorescence light including an excitation light source which emits excitation light, a collecting unit (111) which collects the excitation light emitted from the excitation light source and a fluorescent plate (101) which converts the excitation light collected by the collecting unit (111) into the fluorescence light, and a position of the fluorescent plate (101) is shifted from a position where the fluorescence light is the brightest by a predetermined distance along a light axis direction of the collecting unit (111).</p> |
