    • An image displaying apparatus, comprising: a first light modulator unit, which is configured to modulate a light incident thereon, responding to a first video signal, thereby to form a first image; one or a plural number of second light modulator units, which is/are configured to modulate a light from a light source, responding to a second video signal; and an enlarged image forming unit, being disposed on a light incidence side of the first light modulator unit, upon which a light modulated within the second light modulator unit is projected, enlargedly, thereby to form a second image thereon, wherein upon the first light modulator unit is incident the light of the second image formed on the enlarged image forming unit, and the first image is formed through modulation of the light of the second image responding to the first video signal.

    • 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.
    • 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。
