摘要： An image display apparatus includes a projection unit configured to project an image and a plurality of concave reflectors in which contact surfaces with optical axes of the concave reflectors with respect to the optical axis of the projection unit are disposed at different angles from one another. A first concave reflector of the plurality of concave reflectors reflects at least a portion of an image projected by the projection unit to form a first image based on the image. A second concave reflector of the plurality of concave reflectors transmits a portion of an image projected by the projection unit and reflects a portion of the image to form a second image based on the image.

摘要： An illumination structure attached to a display surface side of a display structure is provided. The illumination structure includes a light guide plate, a coupling member arranged between the light guide plate and the display surface and coupled to the light guide plate, and a light source arranged so as to illuminate a side surface of the light guide plate. The light guide plate includes a first surface in contact with the coupling member and a second surface opposite to the first surface. The second surface of the light guide plate is flat. The first surface of the light guide plate includes a first portion substantially parallel to the display surface and a second portion recessed from the first portion toward the second surface side.

摘要： An illumination device includes a display device, a light-guiding plate, a first coupling member disposed between the display device and the light-guiding plate, a transparent plate, a second coupling member disposed between the light-guiding plate and the transparent plate, and a light source. The light-guiding plate has a first surface in contact with the first coupling member and a second surface in contact with the second coupling member. The first surface is flat. The second surface has a flat part substantially parallel to the display surface and a convex portion that projects from the flat part to the second coupling member side. The convex portion has a first portion inclined to the second coupling member side from upstream to downstream in an emission direction of the light source, and a second portion inclined to the first coupling member side from upstream to downstream in the emission direction.
