    • An image display apparatus includes a light source for emitting illumination light, an image display element for displaying an image by reflecting incident light, an illumination optical element which reflects the illumination light from the light source toward the image display element and through which image light from the image display element is transmitted, an observation optical element for guiding the image light transmitted through the illumination optical element to an eye of an observer, and a light-shielding member for blocking at least one of unnecessary light which is contained in the illumination light from the light source and travels outside an effective image display area of the image display element and unnecessary light which is contained in the image light from the image display element and travels outside an effective observation space.
    • 图像显示装置包括用于发射照明光的光源,用于通过反射入射光来显示图像的图像显示元件,将来自光源的照明光朝向图像显示元件反射的照明光学元件, 发送图像显示元件,用于将透过照明光学元件的图像光引导到观察者的眼睛的观察光学元件,以及用于阻挡包含在照明光中的不必要的光中的至少一种的遮光部件 并且在图像显示元件的有效图像显示区域外面行进,并且来自图像显示元件的包含在图像光中的不必要的光在有效观察空间外行进。
