Abstract:
     The present invention relates to a projection display device, including a light source for produce first illuminating light beam; first lens group; a reflector for reflecting first illuminating light beam to produce second illuminating light beam, and focus it on the image module component; second lens group placed between the light source and reflector; a reflected image module component, including several controllable reflecting surfaces for modulating second illuminating light beam by using reflection mode and a projection lens group for outputting the image-contained projecting beam to pass through first lens group and imaging onto the screen, and the reflecting surface normal of image module component and the plane defined by optical axis of first and second lens groups are non-coincident.
