<p>A polarized-light converting elemental device comprises a mirror glass portion consisting of an array of glass mirror blocks (7) each having a first reflecting optical element (8) and a second reflecting optical element (9) and a cholesteric-liquid-crystal glass portion (1) including a cholesteric liquid crystal layer (3) for reflecting either clockwise circularly polarized component or anticlockwise circularly polarized component and transmitting the other. The device produces outgoing circularly polarized light beams having the same rotation direction and propagating in two different directions. A projection-type display device is also described.</p> |
