ABSTRACT:
A structure for protecting a rod integrator that is used for a projection display apparatus is provided. The structure has: a protecting tube for the rod integrator, the protecting tube accommodating the rod integrator therein, wherein the protecting tube has openings which are defined at positions that face a light incident surface and a light exiting surface of the rod integrator, respectively; and a light shield plate that is provided between the opening and a light source for emitting light to the rod integrator, the opening facing the light incident surface of the rod integrator, wherein the light shield plate has an opening for allowing light to pass therethrough so that the light is incident on the rod integrator.
