Patent ID: 8847854

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 including prisms arranged along one direction 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; a synchronous drive circuit adapted to synchronize said first and second light sources to display parallax images on said transmissive display panel; a phase difference plate; and an optically-modulating structure adapted to receive light emitted from said phase difference plate, said optically-modulating structure comprising: first and second transparent substrates opposing each other; a prism array provided on said first transparent substrate; a first transparent electrode layer provided on said prism array; a second transparent electrode layer provided on said second transparent substrate; a liquid crystal layer provided between said first and second transparent substrates; and first and second alignment layers provided on said first and second transparent substrates, respectively, for performing an aligning process upon liquid crystal molecules of said liquid crystal layer, said phase difference plate adapted to rotate a main polarization angle of said single-face prism sheet by a predetermined angle to coincide with an aligning direction of said liquid crystal layer.
