Improved screen for fixed view projectors essentially characterized by the fact that the incidence of the rays or light beam coming from the spotlight of the projector, after passing through a translucent screen interposed between both elements, affects a reflecting screen located inside a dark camera and in which the reflected image is perfectly visible, whatever the lighting of the place or room where the projection is observed, whether the observation is made directly through the opening provided by the upper box of the projector, as if a transparent glass or crystal is arranged in it.
