Abstract: PROBLEM TO BE SOLVED: To provide a projector which easily removes the unevenness of illuminance occurring on a screen.
SOLUTION: Illuminating light separated into colors by a color division optical system 23 is modulated per color through liquid crystal light valves 25a to 25c. Image light emitted from respective liquid crystal light valves 25a to 25c is synthesized in a light synthesizing optical system 27 and is projected on a main body part 40 of a transmission screen member 18 by a projection lens 29. Since an anti-reflection film 41a is formed on the backside of a Fresnel lens sheet 41 constituting the main body part 40 to perform such transmittance compensation that the power distribution of image light is canceled, the illuminance distribution in a white level of the transmission screen member 18 can be made uniform. Therefore, an image of high quality which has less unevenness of luminance can be observed in the front side of the transmission screen member 18.

Abstract: PROBLEM TO BE SOLVED: To provide an illuminating device improved in the degree of freedom in terms of design such as a light source device being made small in size while completely attaining the uniformization of illuminating light by a rod integrator, and a projector in which the illuminating device is assembled.
SOLUTION: Light source light LG made incident on the incident port IP of an integrator optical system 21c is made incident directly on an opposed inclined end face 63a or made incident on the end face 63a after it is reflected by a pair of end face parts 63c and 63d or the like of a rectangular prism part 63. The light source light LG made incident on the end face 63a is totally reflected by the end face 63a and guided to a rod integrator body 61 after its optical path is bent without loss. Since the optical system 21c guides the light source light LG to the orthogonal rod integrator body 61 by totally reflecting it by the prism part 63, the optionality of the arrangement or the size of the illuminating device 20 is enhanced, consequently the illuminating device 20 is miniaturized.
