Patent ID: 8922726

Claim:
A non-spectacled stereoscopic display apparatus comprising: a light guide plate having a light distributing face, a light emitting face opposing said light distributing face, and first and second light incident faces opposing each other on sides of said light distributing face and said light emitting face; first and second light sources disposed on the first and second light incident faces, respectively, of said light guide plate; a single-face prism sheet disposed on the light emitting face of said light guide plate; a transmissive display panel disposed on a light emitting face of said single-face prism sheet with no air gap therebetween, said transmissive display panel having a polarizing plate opposing the light emitting face of said single-face prism sheet; and a synchronous drive circuit adapted to synchronize said first and second light sources to display parallax images on said transmissive display panel, wherein a polarizing direction of polarization anisotropy of the light emitting face of said single-face prism sheet coincides with a polarizing direction of said polarizing plate, and coincides with a line perpendicular to a direction of optical axes of said first and second light sources, so that a luminous intensity at a light emitting face of said transmissive display panel relative to a luminous intensity at a light incident face of said transmissive display panel is maximum.
