Abstract
A non-spectacled stereoscopic display apparatus includes a light guide plate, first and second light sources, a single-face prism sheet, a transmissive display panel, a synchronous drive circuit adapted to synchronize the first and second light sources to display parallax images on the transmissive display panel, a phase difference plate, and an optically-modulating structure adapted to receive light emitted from the phase difference plate. The optically-modulating structure includes first and second transparent substrates, a prism array provided on the first transparent substrate, a first transparent electrode layer, a second transparent electrode layer, a liquid crystal layer, and first and second alignment layers for performing an aligning process upon liquid crystal molecules of the liquid crystal layer. The phase difference plate is adapted to rotate a main polarization angle of the single-face prism sheet by a predetermined angle to coincide with an aligning direction of the liquid crystal layer.
