The base consists of white resin and includes a plurality of projector side inclined planes and non-projector side inclined planes, which are alternately provided to form the saw-tooth appearance. The projector side inclined planes are oriented so that the image light from the projector may be incident on them, while the non-projector side inclined planes are oriented so that the image light from the projector may not be incident on them. The optical absorption layer is formed on each of the non-projector side inclined planes of the base to absorb the light. The projector side inclined plane reflects the image light just in front of the observer of the reflex-type screen from the projector.
