摘要： The structure of the present invention makes dark lines due to a central axis of a cross dichroic prism sufficiently inconspicuous. A stepped reflecting mirror is interposed between a second lens array and a condenser. The stepped reflecting mirror has the function of deviating the optical path of part of the partial light fluxes among a plurality of partial light fluxes passing through a plurality of small lenses aligned on the same column in lens arrays from the optical path of the other partial light fluxes. A planar transparent member may be used in place of the stepped reflecting mirror for the purpose of deviating the optical path. Another technique shifts part of rows in the lens arrays and to deviate the optical path of part of the partial light fluxes.

摘要： A polarizing illumination device and a projection display device using the polarizing illumination device improve light utilization efficiency. Polarizing conversion elements are placed so that one of polarizing separation films of a first polarizing conversion element and one of polarizing separation films of a second polarizing conversion element are close to each other and so that effective incident areas and ineffective incident areas are alternately arranged in the x direction. The width WP in the x direction of the effective incident areas and the ineffective incident areas is set to be larger than half of the width WL in the x direction of small lenses in a second lens array. The optical axes of each of small lenses are offset from the lens centers thereof so that partial beams emerging from the small lenses in a first lens array optimally enter the effective incident areas where the partial beams should enter.

摘要： All light polarized in random directions is converted into s-polarized light and emitted by a polarizing conversion element 140. Linearly polarized light to be modulated is made incident on three liquid crystal light valves 250, 252, and 254, and p-polarized green light and s-polarized red and blue light are made incident on a cross-dichroic prism 260. Accordingly, for example, .lambda./2 phase plates 310 and 312 are respectively located in the optical paths before the first and third liquid crystal light valves 250 and 254. The .lambda./2 phase plates may be placed at various positions in the optical paths between dichroic mirrors 210 and 212 and the cross-dichroic prism 260.

摘要： The invention provides a dichroic prism capable of reducing displacements of projection pixels of colors caused by chromatic aberration of magnification. A dichroic prism is formed in the shape of a quadrangular prism as a whole by joining four rectangular prisms together. A red reflecting dichroic plane and a blue reflecting dichroic plane intersect to form substantially an X shape along junction surfaces of the prisms. The red reflecting dichroic plane is convex-shaped by partly changing the thickness of an adhesive layer for connecting the rectangular prisms together. Accordingly, since a red beam can be guided to a projection optical system while being enlarged, it is possible to reduce a projection image of the red beam to be projected onto a projection plane via the projection optical system. This makes it possible to reduce relative displacements of projection pixels of color beams caused by chromatic aberration of magnification.
摘要翻译： 本发明提供一种能够减少由倍率色差引起的颜色的投影像素位移的二向色棱镜。 通过将四个矩形棱镜连接在一起，二向色棱镜整体形成为四边形棱镜的形状。 红色反射二向色平面和蓝色反射二向色平面相交，以沿着棱镜的连接表面形成基本上X的形状。 红色反射二向色平面通过部分地改变用于将矩形棱镜连接在一起的粘合剂层的厚度而呈凸形。 因此，由于红色光束可以在被放大的同时被引导到投影光学系统，所以可以通过投影光学系统减少要投影到投影平面上的红色光束的投影图像。 这使得可以减小由倍率色像差引起的彩色光束的投影像素的相对位移。

摘要： An output light from an a light source lamp unit 8 in a projection-type display apparatus illuminates liquid-crystal light valves 925R, 925G and 925B for three colors via an integrator optical system 923. A superimposing lens 930 that is a component of the integrator optical system 923 as a uniform illumination optical system is arranged such that the mounting position of the superimposing lens 930 is fine-adjustable in a direction orthogonal to an optical axis 1a. By fine-adjusting the mounting position of the superimposing lens 930, the position of an illumination area B is adjusted such that the illumination area includes the image forming area A of the liquid-crystal light valve. It is not necessary to assure a wide margin around the image forming area A to cover the offset of the position of the illumination area B. As a result, the utilization of illumination light is heightened and a bright projected image results.
