摘要： 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.

摘要： A display device has a projector having a light guide plate that guides light incident from an end portion and deflects the light guided to emit the light from a projection surface facing a viewer in a first direction, the projector being configured to emit light from the projection surface to project an image in a space viewable by the viewer, and a rotator configured to rotate the projector around the first direction. When a first end on the projection surface is located at a first position being an upper side in a second direction orthogonal to the first direction, the image is viewed as a stereoscopic image by the viewer. When the rotator rotates the projector and the first end is located at a second position different from the first position, the image is viewed as a planar image by the viewer.
