摘要:
A stereoscopic display, by which a viewer can view a stereoscopic image by striping light and giving the striped light to an LCD panel 1 consisting of a display screen containing a group of left eye pixels and a group of right eye pixels, comprises a first light source 4 arranged apart from the LCD panel 1 by a first distance, a second light source 5 arranged apart from the LCD panel 1 by a second distance, a lenticular screen 6 arranged in front of the first and second light sources 4 and 5, a first diffusing plate 7 for diffusing and transmitting light and forming a striped light image from the first light source, a second diffusing plate 8 for diffusing and transmitting light and forming a striped light image from the second light source, wherein a distance of an optimum viewing position from which a viewer can view a stereoscopic image can be changed by switching between a state where the first light source 4 is on and the first diffusing plate has a diffusing effect and a state where the second light source 5 is on and the second diffusing plate 8 has a diffusing effect.

A light source device for use in liquid crystal projectors which comprises a reflector oriented toward a liquid crystal panel and having a reflecting surface formed by a paraboloid or ellipsoid, and a light source disposed at the focal position of the reflector. A converter is disposed on an optical axis extending from the light source to the liquid crystal panel for converging light emanating from the light source and reflected from the reflector in accordance with the size of an image display portion of the panel. The reflecting surface of the reflector has a great focal distance so that the spreading angle of the reflected light is not greater than 8 deg.

In a display device that provides a first observation region with a first picture and provides a second observation region with a second picture, a double image made of the first picture and the second picture is suppressed. First columns of pixels that display the first picture and second columns of pixels that display the second picture are disposed alternately with a black matrix interposed between each neighboring pair of them. A light-shielding plate having light-shielding portions and openings is disposed above the panel. When a distance between the first observation region and the second observation region is denoted by V, a distance between the first observation region or the second observation region and the light-shielding plate is denoted by D, a distance between the light-shielding plate and the display panel is denoted by G, an interval of the first columns of pixels or the second columns of pixels is denoted by P, and the width of the black matrix is denoted by Q, an equation K≦Q×D/(D+G) is satisfied. The openings are disposed on lines connecting between a position directly above a center of the display panel and the black matrix.

A display device includes: a two-dimensional display unit that displays p viewpoint videos, which are spatially divided, within one screen; and an optical device that optically splits the p viewpoint videos displayed on the display unit so as to enable a stereoscopic view at p viewpoints. The display unit includes unit pixels each formed from sub-pixels that display r types of colors necessary for a color video display, and the sub-pixels that emit light of different colors are arranged so as to be adjacent to each other in a same row in a screen horizontal direction. Each of the p viewpoint videos is displayed in n sub-pixel rows, each of which is configured by the sub-pixels aligned in a first direction other than the screen horizontal direction and which are consecutive in the screen horizontal direction, in the screen horizontal direction on a cycle of (p×n) rows.
