Abstract: Disclosed 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 fluorescent plate including a fluorescence emission region on a surface of a circular substrate which emits the fluorescence light by the fluorescence emission region being irradiated with the excitation light from the excitation light source, a drive unit which rotates the fluorescent plate in a circumferential direction and a control unit which controls the excitation light source and the drive unit. And the control unit controls the drive unit so that a display frequency of the display element and a rotation frequency of the fluorescent plate fulfill formula (1) j×display frequency=k×rotation frequency (j, k are integers, j>k)  (1).
