With respect to partial display regions 14, 15, 16, . . . of the spatial light modulator that correspond respectively to partial light-emitting regions 6a, 6b, 6c, . . . defined by dividing the light-emitting surface, the control device switches each of the partial display regions 14, 15, 16, . . . between a normal image display state and an OFF state for cutting off light, in synchronization with passing of boundary lines 51, 52 and 53 between each pair of adjacent ones of the color filters of the rotary color filter over each of the partial light-emitting regions 6a, 6b, 6c, . . . . Thus, the efficiency of using illumination light by the spatial light modulator is improved, and it is possible to achieve an increased color luminance of a projected image, while sufficiently maintaining an effect of preventing color mixing from being caused by adjoining color filters.

摘要： An illuminating optical system for focusing a radiant light of a light source (1) onto a reflecting light valve (6) and a projection lens (7) for magnifying and projecting a reflected light from the reflecting light valve (6) onto a screen are provided, a diaphragm (31) is disposed at a substantially conjugate position of an entrance pupil of the projection lens (7) on an optical path of the illuminating optical system, the diaphragm (31) has an opening whose area is changed by a light-shielding member, and a shape of a shielded portion of the diaphragm (31) shielded by the light-shielding member is rotationally asymmetric to an optical axis (12) of the illuminating optical system. Accordingly, shielding of necessary light can be better avoided compared with a diaphragm for changing the light-shielding area in a rotationally symmetric manner, for example, a diaphragm for narrowing the opening concentrically, making it possible to improve contrast performance while minimizing brightness reduction.

The substrate is arranged so as to receive the incident light obliquely thereto. When the incident angle and the thickness of the optical thin film are optimally selected, the transmittance for the P polarized light can be made approximately 100%, while that for the S polarized light very small. The polarizer can extract a substantially linearly polarized light from natural light, A projection image display system has the polarizer as its pre-polarizer.
