PROBLEM TO BE SOLVED: To accurately align a light transmission plate with a mask or a lens array for displaying a stereoscopic image, and facilitate positioning.SOLUTION: The display device 1 includes: the light transmission plate 2; a light source 5 provided on an end face 2a of the light transmission plate 2; and the mask 3 or the lens array provided on a surface 2b side of the light transmission plate 2. A reflection scattering part 24 for reflecting and scattering light from the light source 5 that is made incident from the end face 2a and emitting it to the surface 2b side of the light transmission plate 2 is formed on the light transmission plate 2, so as to display a predetermined pattern for each viewpoint formed by light emitted through the mask 3 or the lens array from the reflection scattering part 24. The light transmission plate is provided with a positioning mechanism 4 positioning the light transmission plate 2 and the mask 3 or the lens array by fitting each other at a portion where the light transmission plate 2 faces the mask 3 or the lens array. |
