ABSTRACT:
There is provided a stereoscopic video display that enables a viewer to recognize a more real stereoscopic video.A light source device2comprises a backlight21and a pinhole array plate22. A liquid crystal display panel driver5feeds a pixel driving signal to a liquid crystal display panel3, to form a pixel region3acomposed of a plurality of pixels respectively corresponding to pinholes22a. Each of the pixels composing the pixel region3acontrols an amount of light transmission with respect to a light beam in each direction from the corresponding pinhole22a. Consequently, the intensity of the light beam in each direction is reproduced. Lines respectively connecting the centers of the pinholes22aand the centers of the pixel regions3aare not parallel to one another, and are so set as to cross at one point of a position corresponding to the standard distance between the video display panel3and a viewer Z. Therefore, the light beams are efficiently concentrated at a standard viewing position, thereby making it possible to make the viewer Z recognize a more real stereoscopic video.
