[0068] The prism portion 34 can reflect an image incident from the bottom side backward at the total reflection surface 37 when the cover window 3 is laid flat, and the image reflected at the total reflection surface 37 can be emitted backward.

[0069] The material of the cover window 3 having the prism portion 34 may be a transparent ceramic series (glass, quartz, etc.) or a transparent polymer series (acrylic acid, PS (polystyrene), epoxy resin, PC (polycarbonate), etc.).

[0070] The prism portion 34 may not perform a separate surface treatment on the total reflection surface 37 , but may perform a surface treatment such as vapor deposition or printing on the total reflection surface 37 in order to improve brightness.
