Abstract
A first light guide plate and a second light guide plate are arranged facing each other. A microprojection group comprising a plurality of microprojections is arranged in the visual recognition region of the surface facing the first light guide plate in the second light guide plate. The plurality of microprojections have a height and arrangement that ensure a distance where interference fringes are not visually recognized between the first light guide plate and the second light guide plate in contact with the second light guide plate. The microprojection group and the dimples configuring a design part formed on the second light guide plate are formed on an identical surface.
