    • A projection-type image displaying apparatus takes in outside air through an air inlet formed in a housing unit to cool at least one of an optical modulator and an optical element that are accommodated in the housing unit, the optical modulator forming an optical image and the optical element being disposed between the optical modulator and a light source. The projection-type image displaying apparatus includes a cooling fan, a first dustproof filter disposed at the air inlet of the housing unit, a second dustproof filter disposed in a flow path that guides the outside air toward the optical modulator or the optical element after the outside air passes through the first dustproof filter and the cooling fan, and a holder for holding the optical modulator or the optical element, the holder having an outside-air introducing portion, wherein the second dustproof filter is attachable to the outside-air introducing portion.
    • 投影型图像显示装置通过形成在壳体单元中的空气入口吸入外部空气,以冷却容纳在壳体单元中的光学调制器和光学元件中的至少一个,形成光学图像的光学调制器和 光学元件设置在光调制器和光源之间。 投影型图像显示装置包括冷却风扇,设置在壳体单元的空气入口处的第一防尘过滤器,设置在流过路径的第二防尘过滤器,该过滤器在外部空气朝向光学调制器或光学元件之后引导 外部空气通过第一防尘过滤器和冷却风扇,以及用于保持光学调制器或光学元件的保持器,具有外部空气导入部的保持器,其中第二防尘过滤器可附接到外部空气引入部分 。
