Abstract: For example, a semi-spherical system holding mechanism 8 such as to cover the head portion of the user is provided in the upper portion of a user holding mechanism 9 such as chair, sofa, or the like. A display apparatus 7 is fixed in the system holding mechanism 8. In the display apparatus 7, a video image displayed on a display panel 14 is enlarged by a lens 13, so that a virtual image is formed. The virtual images which are observed by the right and left eyes of the user are arranged at the same position in a space.

Abstract: To relieve fatigue of viewer's eyes, a binocular display system is equipped with a mechanical or electrical adjusting section for minimizing a separation between left and right virtual images for the left and right eyes. The adjusting section holds the arrangement of the four positions of left and right lenses (or curved mirrors) and left and right pictures produced by at least one display device in such a manner as to reduce the separation between the left and right virtual images of the left and right picture substantially to zero, and/or adjusts the arrangement of these four positions to move the left and right virtual images in a desired direction so that the left and right images remain optically coincident.

Abstract: PROBLEM TO BE SOLVED: To enable an observer to view an image having no right and left cross talk even when the head of the observer vertically moves, in a stereoscopic image display device configured by disposing a liquid crystal layer 33 where a right-eye pixel area 31 and a left-eye pixel area 32 are alternately formed and a space division filter 6 where a wavelength plate ineffective area (non-rotation area in the polarizing direction) and a wavelength plate effective area (rotation area in the polarizing direction) 28 are alternately formed correspondingly to the light transmission paths of the pixel areas 31 and 32 of the liquid crystal layer 33, between a light source and an observer. SOLUTION: A light beam non-transmission area 30 is formed in a boundary portion between the right-eye pixel area 31 and left-eye pixel area 32 of the liquid crystal layer 33. Even when the position of the head of the observer moves upward and consequently a light beam reaching the eyeballs changes from 15 to 16, an optical component where a right-eye image and a left-eye image are mixed is blocked by the light beam non-transmission area 30.

Abstract: PROBLEM TO BE SOLVED: To provide a virtual image with a shape suitable to a video.
SOLUTION: In the case a video is broadcasted as a movie and a drama having an aspect ratio of 16:9 by a high definition television broadcast, in the display device 4, a large virtual image is formed in a position far away from a user by about 15m. Alternatively, in case that a video is broadcasted as a television signal having an aspect ratio of 4:3 by an NTSC system, in the display device 4, a middle-sized virtual image is formed in a position comparatively close to the user by about 3m. Whether the video is broadcasted by the high-definition television broadcast or the NTSC system is decided based on the synchronizing signal of the television signal.

Abstract: PROBLEM TO BE SOLVED: To prevent a user from sensing flickers, even when observing an environment around a display surface in a time division type three-dimensional(3 D) display system, and to enable the user to observe a screen which is has several times the brightness of a conventional system. SOLUTION: A linearly polarized light filter 31 is fitted to the display surface of a CRT 1. Liquid crystal shutter glasses are constituted of two linearly polarized light filters 32, arranged oppositely to respective observer's eyeballs, i.e., the left eye 100L and the right eye 100R and glass plates 33, sealed with liquid crystal which are arranged on the CRT 1 sides of the filters 32. The transmission and cut-off of the right and left eye liquid crystal shutters of the shutter glasses are switched synchronously with the vertical scanning timing of a video signal. Each shutter glass acts as a shutter for the eyeball (e.g., 100L) in a visual field angle range A to the display surface of the CRT 1, however, the glass has no shutter filter for visual field angel ranges B, C other than the display surface of the CRT 1, so that the observer can observe the surrounding environment in a natural manner without sensing flickers.
