<p>The invention relates to providing a projector having a structure capable of easy miniaturization although the projector is capable of achieving a smooth moving picture display of good quality. A projector including: an illuminating apparatus 100; a color separating optical system 200; liquid crystal display devices 400R, 400G and 400B; and a projecting optical system 600, the projector further including: a shielding member 160, which is provided in the vicinity of a light emitting surface of a first lens array 120 and in which a light transmitting area 162 and a light non-transmitting area 164 are alternately arranged in an optical path in a first direction vertical to an optical axis of illumination 100ax; and a rotating prism 770, which is provided between a superimposing lens 150 and the color separating optical system 200, for scanning an illuminating light bundle in image forming areas of the liquid crystal display devices 400R, 400G and 400B synchronously with screen writing frequencies of the liquid crystal display devices. <IMAGE> <IMAGE></p> |
