Abstract
A stereoscopic display device is provided. The stereoscopic display device includes an optical waveguide member and a first main surface and a second main surface. The first and second main surfaces face each other. A first light path changing member is provided on at least one of the first and second main surfaces, and is operative to change the path of light guided by the optical waveguide member. A second light path changing member is provided on at least one of the first and second main surfaces, and is operative to change the path of the light guided by the optical waveguide member. A reflector body is disposed so as to face the second main surface and reflects the light emitted from the second light path changing member to the first main surface.
