ABSTRACT:
A reflective plate is offered which is capable of forming an exit region of reflected light in an effective field of view area in an obliquely above or below position. The reflective plate has plural reflective subregions each having reflective surfaces for reflecting light. Light rays reflected from the reflective subregions form plural spreads of exit which intersect each other at a given upper position to thereby form a common exit region. The reflective subregions are so arranged that light entering the reflective plate from a vertical direction is reflected by the reflective subregions substantially toward the center of the exit region lying outside a region that is vertically above the reflective plate. The centers of the intensities of the reflected light rays concentrate at the center of the exit region.
