  • Publication number: 20080239484
    Abstract: A polarized light transmission screen and a stereoscopic image displaying apparatus capable to display a clear stereoscopic image with few little cross talks over a wide wavelength range. In a polarized light transmission screen 30, a 90-degree rotation regions 32b include in piles a plurality of retarders of which the directions of the optical axes differ with one another, and when the linearly polarized light having a polarization axis of a specific direction is made to be transmitted, they rotates the polarization axis by 90 degrees in total by each of the plurality of retarders rotating the polarization axis less than 90 degrees in steps. A 0-degree rotation regions 32a include in piles a plurality of retarders of which the directions of the optical axes differ with one another, and when the linearly polarized light having a polarization axis of a specific direction is made to be transmitted, the polarization axes of incidence and emission are the same direction.
