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 liquid crystal display device has a first backlight unit and a second backlight unit. The first backlight unit includes a first optical member that transmits light incident from the second backlight unit, converts light output from a light source to light having a narrow-angle directional distribution, and radiates the converted light toward the rear surface of the liquid crystal display panel. The second backlight unit includes a second optical member that converts light output from a light source to light having a wide-angle directional distribution, and radiates the converted light toward the rear surface of the liquid crystal display panel.
