Patent ID: 7356211

Claim:
A stereoscopic display device comprising: an optical waveguide member that has an end surface on which light emitted from a light source is incident; a first main surface and a second main surface, the first and second main surfaces face each other; a first light path changing member that is provided on at least one of the first and second main surfaces, and being operative to change the path of light guided by the optical waveguide member; a second light path changing member that is provided on at least one of the first and second main surfaces, and being operative to change the path of the light guided by the optical waveguide member; and a reflector body that 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, wherein the first light path changing member is provided on the first main surface and is formed of a light diffusing part that diffuses light guided by the optical waveguide member, and the second light path changing member is provided on the first main surface and is formed of a prism that changes the path of the light guided by the optical waveguide member so as to travel toward the second main surface.
