Abstract: PROBLEM TO BE SOLVED: To solve the problem that a projector incorporating two color wheels and switching the color wheels to be partially superposed on an optical path is difficult to be made small in size with durability. SOLUTION: The projector 100 is equipped with a light source device 210, a light source optical system 220, a display element 230, a projection side optical system 250, a cooling fan 190, and moreover, a lamp power supply circuit 261, a fan driving power supply circuit 263, and a projector control means 267. The projector 100 is equipped with two color wheels in four colors, including three primary colors of red, green and blue filters and a transparent or white filter, and with wheel motors (275, 276) to rotate one of the two color wheels (221, 222) by using the position of the color wheels (221, 222) placed on the optical path with the transparent or white filters of the two color wheels (221, 222) superposed as a reference.
