Reflective plate, liquid crystal display (LCD) using same, and electronic apparatus using this LCD

摘要

A reflective plate is disclosed which forms an overlap region defined by its reflected light which acts as an effective field of view at a position obliquely above the plate. The reflective plate has plural reflective subregions (13) each having reflective surfaces for reflecting light. Light rays reflected from the reflective subregions form plural diverging beams which intersect each other at a given upper position to thereby form a common overlap region. The reflective subregions are so arranged that light incident on the reflective plate from a vertical direction is reflected by the reflective subregions substantially toward the centre (12) of the overlap region located above and beyond the reflective plate. The centres of the intensity distributions of the reflected light rays meet at the centre of the overlap region. <IMAGE>
