Abstract
A projection display system can display large projected images onto a projection surface in a small space or a small room without occupying a space over a table or a desk placed therein, and can easily be detachably mounted in place and carried around. A projector installation fixture is mounted on a side end of an upper surface panel of the table or the desk near the projection surface, and a front-projection projector is detachably installed in place by the projector installation fixture. The front-projection projector has an optical system including an aspherical mirror at a final stage thereof.
