Optical prism for projecting image |
摘要 |
An optical prism (1) for reflecting incident light from an incidence surface (2) suited for incidence of light from an LCD (20) or the like for at least twice before emitting the reflected light as emission light from a predetermined emission surface (4). The optical prism has side surfaces (6L and 6R) crossing the incidence and emission surfaces (2 and 4) and including receded surfaces 7L and 7R) formed such as not to impede an optical path of an effective size, the incident light being led along the optical path from the incidence surface to the emission surface.
