Abstract
There is provided a stereoscopic video display that enables a viewer to recognize a more real stereoscopic video. A light source devicecomprises a backlightand a pinhole array plate. A liquid crystal display panel driverfeeds a pixel driving signal to a liquid crystal display panel, to form a pixel regioncomposed of a plurality of pixels respectively corresponding to pinholes. Each of the pixels composing the pixel regioncontrols an amount of light transmission with respect to a light beam in each direction from the corresponding pinhole. Consequently, the intensity of the light beam in each direction is reproduced. Lines respectively connecting the centers of the pinholesand the centers of the pixel regionsare 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 paneland 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.
