    • According to the present invention, there is provided an image display device including a non-luminous reflection type spatial light modulating element, illuminating system to illuminate the reflection type spatial light modulating element and a projection lens and in which light from a light source (2) illuminates the reflection type spatial light modulating elements (14, 15) via first and second fly-eye integrators (9, 10). An unnecessary part, not modulated, of the light reflected by the reflection spatial light modulating elements (14, 15) and further by a reflector (4) for recycling. Since the fly-eye integrators (9, 10) are displaced in relation to their optical axes, it is possible to utilize the light with an improved efficiency and prevent any nonuniform illumination from taking place.
    • 根据本发明,提供一种图像显示装置,其包括非发光反射型空间光调制元件,照明反射型空间光调制元件的照明系统和投影透镜,其中来自光源(2)的光 )经由第一和第二飞眼积分器(9,10)照射反射型空间光调制元件(14,15)。 由反射空间光调制元件(14,15)反射的光以及进一步由用于再循环的反射器(4)的光的不被调制的不必要部分。 由于蝇眼积分器(9,10)相对于它们的光轴移位,所以可以以提高的效率利用光,并且防止发生任何不均匀的照明。
