Stereoscopic image display device
A stereoscopic image display device comprising: a display device to include a display surface; a first optical unit to be installed in parallel to the display surface adjacently to the display surface of the display device, one surface including a first convex portion via which to form an image of light emerging from the display surface at a first image forming point and a first flat surface portion, and the other surface being a flat surface; and a second optical unit to be installed in parallel to the first optical unit adjacently to the first optical unit, one surface including a second convex portion via which to form the image of light emerging from the display surface at a second image forming point different from the first image forming point and a second flat surface portion, and the other surface being the flat surface.
