    摘要： A projection apparatus includes an optical engine (10) that projects an image on a screen from a rear side, an engine supporting plate (100) on which the optical engine (10) is placed, an adjusting member (500) of a substantially wedge-shape inserted into between a base portion (11) and a lower surface of the engine supporting plate (100) so that front or rear end of the engine supporting plate (100) is vertically rotatable, a front-to-rear position adjusting unit (56) capable of moving the adjusting member (500) in front-to-rear direction, a slope portion (108) having a slope surface (109) that gradually increases or decreases an angle of a surface of the adjusting member (500) contacting the engine supporting plate (100) in accordance with a movement of the adjusting member (500), and a fixing unit (551, 552) that fixes the engine supporting plate (100) to an adjusted position.

    摘要： A rear projection type display apparatus includes a base in which an optical unit and an electrical circuit are accommodated and which has an opening at a rear side thereof, and a cabinet which supports a mirror and a screen and which is mounted to an upper side of the base. The base has a first connecting portion provided along at least one side of the opening, and the cabinet has a second connecting portion which engages the first connecting portion of the base along at least one side of the opening. One of the first connecting portion and the second connecting portion has a cross sectional shape which includes two facing inner walls and which is opened in one direction.

    摘要： A planar light source device includes a first light source for emitting a first light ray having a punctate spatial luminance distribution; a second light source for emitting a second light ray; a first spatial luminance distribution conversion portion for changing the first light ray to a linear spatial luminance distribution; a second spatial luminance distribution conversion portion for changing a spatial luminance distribution of the first and second light rays to a planar spatial luminance distribution; wherein the first light ray is a laser light; the second light ray has a divergence angle larger than the divergence angle of the first light ray when the first light ray is emitted from the first light source; and a slow-axis direction of the first light ray entering the second spatial luminance distribution conversion portion is parallel to an outgoing direction of the planar light.
