Abstract
A non-spectacled stereoscopic display apparatus includes: a light guide plate having a light distributing face, a light emitting face, and first and second light incident faces; first and second light sources disposed on the first and second light incident faces, respectively; a single-face prism sheet disposed on the light emitting face of the light guide plate; a transmissive display panel disposed on a light emitting face of the single-face prism sheet with no air gap therebetween, the transmissive display panel having a polarizing plate opposing the light emitting face of the single-face prism sheet; and a synchronous drive circuit adapted to synchronize the first and second light sources to display parallax images on the transmissive display panel. A polarizing direction of polarization anisotropy of the light emitting face of the single-face prism sheet coincides with a polarizing direction of the polarizing plate.
