DISPLAY DEVICE AND PRODUCTION OF DISPLAY SCREEN

摘要

PURPOSE:To provide a display device by which different videos can be distinctly and separately viewed from different directions and to improve the quality of the displayed video. CONSTITUTION:By projecting and displaying the projected video from plural projecting devices 101 to a display screen 100 where the diffusion angle or the diffusing degree of light two-dimensionally differs according to projection angle, the projected video is separately and uniformly displayed in a direction corresponding to the projection angle. The plural videos projected and displayed on the display screen 100 are condensed toward an observer by providing a convex lens, so that the display luminance of the display screen surface is made uniform and image quality is improved. The display screen 100 is produced by using a radial light beam having the same irradiation angle as the projection angle at the time of projecting and displaying the video by the porjecting device 101 in the case of photosetting resin composition, and photosetting the plural resin compositions having different refractive index corresponding to the projection angle at the time of projecting and displaying the different videos from the plural projecting device.
