摘要： A screen assembly and a rear-projection type graphic display device are provided to block overscanned light Lo projected outside a fresnel lens screen. The screen assembly 20A includes the fresnel lens screen 21, a screen retainer 22 and a light blocking member 23. The fresnel lens screen 21 forms an image on the side of a front surface 21b by image light Le incoming through a back surface 21a. The screen retainer 22 has a back surface 22a whose area is larger than the back surface 21a and the front surface 21b and which is opposed to the front surface 21b to hold it, and a front surface 22b located on opposite side of the back surface 22a to allow an image formed by the image light incoming through the back surface 21a to be visible through the front surface 22b. The screen retainer 22 has an optical transparency. The light blocking member 23 is arranged so as to surround respective side surfaces of the screen 21 in the form of a frame. At least part of the light blocking member 23 is arranged so as to project to the side of the back surface 21a of the screen.

摘要： A projection type display device includes a image displaying element having image display areas for displaying a plurality of images respectively, a projection optical system having an emitting part for emitting projection light flux to the image display areas of the image displaying element, and a plurality of screens for displaying projected images by the projection light flux transmitted through the image display areas of the image displaying element. In the projection type display device, the image display areas are formed in respective areas in the image displaying element independent of each other. The projected images on the screens correspond to the image display areas, respectively. Each of the screens is arranged in such a position that the each of the screens is not overlapped with shadows of the other screens which are produced since the projection light flux is emitted from the emitting part to the screens.

摘要： Stereoscopic or 3D glasses include a half-wave phase difference plate, a first polarization-converting optical system, and a second polarization-converting optical system. The half-wave phase difference plate is movable between a used position and an unused position. The first polarization-converting optical system follows the half-wave phase difference plate when the half-wave phase difference plate is in its used position. The first polarization-converting optical system is uncovered when the half-wave phase difference plate is in its unused position. When the half-wave phase difference plate is in its used position, the glasses operate in a two-dimensionally viewing mode. When the half-wave phase difference plate is in its unused position, the glasses operate in a three-dimensionally viewing mode.
