    Abstract: A projection type display device includes: a light source (21); a spatial light modulation element (25) for modulating the incident light according to the video signal applied and emitting it; an illumination optical system (23) for collecting light from the light source (21) and illuminating the spatial light modulation element (25); a projection lens (27) for projecting the emission light from the spatial light modulation element (25); light shading means (1) arranged for the spatial light modulation element (25) along the light path of the side of the illumination optical system (23) or the projection lens (27) so as to change the light shading amount of the light passing; and video signal correction means (3, 4, 5, 6) for performing correction of the video signal applied to the spatial light modulation element (25) according to the current light shading amount of the light shading means (1) for each of the regions into which the screen of the spatial light modulation element (25) is divided. Thus, it is possible to perform appropriate uniformity correction even when the light angle distribution emitted from the spatial light modulation element and reaching the screen changes.

    Abstract: In an optical apparatus a first multi-lens array (MLA) (131) forming an integrator optical system is arranged integrally at the light emitting part of a reflecting and condensing mirror (12) so as to function as a surface plate. Due to this, the distance between the effective reflecting part of the reflecting and condensing mirror and the first MLA can be shortened. As a result, as the optical path of the optical system becomes short, it becomes possible to make the optical system of a projector small. In addition, being formed integral to function as a surface plate of the reflecting and condensing mirror, the number of optical elements is reduced by one. Accordingly the loss of light due to surface reflection (Fresnel reflection) occurring on a boundary surface having a difference of refractive indexes is decreased, a larger amount of light can be directed to the SLM and the screen, therefore a projector of a high luminance is achievable.

    Abstract: A projection-type display device includes: a light source 21; a spatial light modulation element 25 which modulates incident light according to an applied image signal and emits the modulated light; an illumination optical system 23 which condenses light from the light source 21 and illuminates the spatial light modulation element 25; a projection lens 27 which projects the light emitted from the spatial light modulation element 25; shielding unit 1, positioned along the path of light on the side of either the illumination optical system 23 or the projection lens 27 with respect to the spatial light modulation element 25, and which can change the amount of shielding of transmitted light; and image signal correction units 3, 4, 5, and 6 which divide the picture plane of the spatial light modulation element 25 into a plurality of areas, and perform correction on the image signal applied to the spatial light modulation element 25 according to the current shielding amount of the shielding unit 1 for each of the plurality of areas. Accordingly, appropriate uniformity correction is performed even when there is a change in the angular distribution of light emitted from the spatial light modulation element and reaching the screen.
