摘要： A stereoscopic image display apparatus includes an image display apparatus main body and a multi-angle image information generating unit for generating image information for a plurality of viewing angles from which a three-dimensional object is viewed. The image display apparatus main body includes a liquid crystal panel for displaying an angle-specific image derived from the angle-specific image information supplied from the multi-angle image information generating unit, and an angle-specific image radial distribution unit which, provided at the front of the liquid crystal panel, radially distributes the angle-specific image by providing directivity to a light beam carrying the angle-specific image displayed on the liquid crystal panel and thus directing the angle-specific image to a corresponding angle. When a viewer changes a view position or viewing angle, the viewer can experience one stereoscopic image turning into another. Thus, different aspects of the three-dimensional object are disclosed so that an extremely realistic stereoscopic vision that gives an impression that the three-dimensional object is actually behind the stereoscopic image display apparatus is provided.

摘要： A virtual screen display apparatus includes a display arranged to generate display information and having an effective diagonal length DLC and an optical projecting element arranged to receive the display information from the display and to project and form an image, the optical projecting element having an effective F number which is defined by Fe=S1/PuD wherein S1 is a distance between the display and a principal point of the optical projecting element and PuD is a diameter of an exit pupil of the optical projecting element. A field optical element arranged to form an in-space image in a position of a virtual screen and to direct a divergent light flux from the virtual screen to a view region where the image is viewable to an observer. A diameter of a range in which the image is viewable to the observer in the view region is ERD and a diagonal length of the virtual screen is VSD and a distance between the virtual screen and the view region is VSP, and the following equation is satisfied: VSD/VSP=DLC/(ERD×Fe).
