摘要： An optical scanning device includes: a light source unit configured to emit a light beam; a light deflecting unit configured to two-dimensionally deflect the light beam in a main scanning direction and a sub-scanning direction orthogonal to the main scanning direction; and an image formation unit configured to form an image by two-dimensional scanning of the light beam performed by the light deflecting unit, in which a flat plate configured to transmit light incident on the light deflecting unit and deflected reflection light from the light deflecting unit is arranged in an optical path of the light beam between the light deflecting unit and the image formation unit, and the flat plate is inclined with respect to the image formation unit in a cross section in the sub-scanning direction. As a result, a high-contrast intermediate image can be formed even if unnecessary light intrudes, and a virtual image with good image quality can be stably displayed.

摘要： An image display device includes an image forming unit configured to emit light forming an image; and a concave mirror configured to reflect the light emitted from the image forming unit toward a transparent reflecting member. The image forming unit includes a transparent member on which the image is formed or which forms the image, the transparent member being curved bulging toward the concave mirror.
