    • PROBLEM TO BE SOLVED: To provide a singular condensing optical element capable of propagating and condensing light made incident from different positions by reversely utilizing an operation principle of a light guide plate to be used for a backlight or the like. SOLUTION: The condensing optical element 10 is constituted by integrally forming a light guide body 10A and a light guide body 10B. Light made incident from an incident part at a predetermined angle is propagated while being totally reflected between an incident surface 12 and a reflecting surface 14. In the wedge-like light guide body 10A, propagated light is converted from a high-order mode into a low-order mode so as to be parallel light and passed through a transmission surface 13. Light made incident from the transmission surface 13 to the light guide body 10B is propagated while being totally reflected between the incident surface 12 and the reflecting surface 14. In the reverse wedge-like light guide body 10B, propagated light is converted from the low-order mode into the high-order mode and condensed in a horizontal direction. Light converted into the high-order mode and condensed to an outgoing part 18 is extracted from the outgoing part 18 over a critical angle. COPYRIGHT: (C)2011,JPO&INPIT
