Luminous intensity distribution control device and display having the same

摘要

It is possible to eliminate a fringe pattern produced at the time of incidence of polarized light of a light distribution control element, in which stray light derived from outside unnecessary light in a liquid crystal display apparatus of the like can be effectively reduced, and bright, wide viewing angle characteristics can be achieved when the display is viewed at any angle by an observer. In a light distribution control element constituted of a transparent base member, an array of a plurality of micro-lenses (transparent beads densely arrange on the transparent base member and a light absorbing layer having very small opening portions substantially at focal positions of the micro-lenses, the transparent base member is constituted of a transparent body which is substantially isotropic optically or a transparent body having uniaxial optical anisotrophy.
