    • An image display device includes a first optical modulator that modulates a plurality of color lights coming from a light source, a color combination member that combines the color lights, a second optical modulator that modulates a light provided by the color combination member as a result of the color light combination, and a relay optical system that is disposed between the color combination member and the second optical modulator. The replay optical system guides the light provided by the color combination member to the second optical modulator. A light transmissive member is disposed between the relay optical system and the second optical modulator, and allows optical path conditions from the first optical modulator to the relay optical system via the color combination member to be substantially the same as optical path conditions from the relay optical system to the second optical modulator.
    • 图像显示装置包括:调制来自光源的多个彩色光的第一光学调制器,组合彩色光的彩色组合部件;第二光学调制器,其调制由所述颜色组合部件提供的光作为 所述彩色光组合,以及设置在所述颜色组合构件和所述第二光学调制器之间的中继光学系统。 重放光学系统将由颜色组合构件提供的光引导到第二光学调制器。 透光构件设置在中继光学系统和第二光学调制器之间,并且允许从第一光学调制器到中继光学系统经由颜色组合构件的光路条件与来自中继光学器件的光路条件基本相同 系统到第二光调制器。

    • An image display device that displays an image by modulating a light from a light source according to display image data, includes: a first light modulation element that modulates a light emitted from the light source; and a second light modulation element that is disposed on an optical path in series with the first light modulation element and modulates a light exiting from the first light modulation element, wherein the first light modulation element and the second light modulation element are disposed in such a manner that a bright-field direction of an optical image of the first light modulation element and a bright-field direction of the second light modulation element almost coincide with each other.
    • 一种图像显示装置,其通过根据显示图像数据调制来自光源的光来显示图像,包括:第一光调制元件,其对从所述光源发出的光进行调制; 以及第二调光元件,其配置在与所述第一光调制元件串联的光路上,并且调制从所述第一光调制元件出射的光,其中,所述第一光调制元件和所述第二调光元件配置在 使得第一光调制元件的光学图像的亮场方向和第二光调制元件的亮场方向彼此几乎一致的方式。
