Abstract
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.
