摘要： A technique is provided that improves the usage ratio of light in the illumination optical system of an image display apparatus. The cross-sectional size or shape of the flux of light that has formed a light source image of an LED-based light-emitting section is converted by anamorphic optics, such as collimator lens, into a size or shape appropriate for an aperture in the portion that permits the flux of the light source image to pass through, in an optical system leading to an image display element(s), and thus the quantity of fluxes of light passed through the aperture is increased.

摘要： A compact rear projection image display apparatus in which the projection distance in a projection optical system is substantially reduced and no reflection mirror is used, thereby eliminating a major cause of image trapezoidal distortion. The rear projection image display apparatus has a projection lens system which includes a first lens group with positive refractive power and a second lens group which further enlarges an image enlarged by the first lens group. The projection lens system enlarges and projects an image displayed on an image display device, on a transmission screen. No reflection mirror is provided between the second lens group and the transmission screen and the image enlarged by the second lens group is directly projected on the transmission screen.

摘要： The present invention provides a projection type image display device capable of affording a bright display of a high saturation and capable of ensuring a high reliability of optical parts. The projection type image display device is provided with a color synthesizer for color-synthesizing modulated and polarized light of red light, green light, and blue light, outputted from an image display element. The color synthesizer has an optical characteristic such that the transmittance including reflection by a reflecting film in the interior of the color synthesizer becomes highest for the polarized light of blue light out of the modulated and polarized light of red light, that of green light, and that of blue light. The color synthesizer also has an optical characteristic such that the quantity of the polarized light of blue light outputted becomes largest out of the modulated and polarized light of red light, green light, and blue light.

摘要： A projection optical unit has two lens groups. A first projection optical unit disposed closest to an image display element, temporarily forms a first enlarged image (magnification: M1) at the image display element side, rather than at a second projection optical unit. The first enlarged image is subsequently projected in an enlarged form (magnification: M2, wherein M2>M1) onto a screen via the second projection optical unit. A field lens group having positive refractive power is disposed between the first projection optical unit and the second projection optical unit. Consequently, the relationship between F2, which is the F-value of the second projection optical unit, and F1, which is the F-value of the first projection optical unit, becomes F2=F1/M1, whereby it is possible to realize very-wide-angle imaging at a field angle exceeding 90 degrees.
摘要翻译：投影光学单元具有两个透镜组。靠近图像显示元件设置的第一投影光学单元在图像显示元件侧暂时形成第一放大图像（倍率：M1），而不是在第二投影光学单元处形成。随后经由第二投影光学单元以放大的形式（倍率：M2，其中M2> M1）将第一放大图像投影到屏幕上。具有正折光力的场透镜组设置在第一投影光学单元和第二投影光学单元之间。因此，作为第二投影光学单元的F值的F2与作为第一投影光学单元的F值的F1之间的关系变为F2 = F1 / M1，从而可以非常实现场角超过90度的全角度成像。
