Patent ID: 6903876

Claim:
A display comprising as the light-guiding body, there is used a divided light-guiding body, having such a construction that a virtual elliptic light-guiding body, formed of a first ellipse having a first focal point and a second focal point and a second ellipse having a third focal point and a fourth focal point, is divided at a focal point corresponding to the second focal point, and at an end of the light-guiding body formed by the segmentation, there are formed a plane of incidence perpendicular to the optical axis of the light entering the end and a total reflecting surface which totally reflects the light entering from the plane of incidence, so that the end becomes thin, wherein the virtual elliptic light-guiding body having an arrangement such that, the second focal point and the third focal point overlap each other, and having a construction such that a first concave reflecting surface and a second concave reflecting surface are arranged on the same side with respect to a virtual line connecting the first to the fourth focal points, and a pair of flat reflecting surfaces facing each other is formed between the first concave reflecting surface and the second concave reflecting surface, so that the light reflected by the first concave reflecting surface passes through a focal point corresponding to the second focal point, located between the pair of reflecting surfaces, towards the second concave reflecting surface, while being reflected by the pair of flat reflecting surfaces.
