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.

Light emitting display device including microprojection group and plurality of microrecesses, method for producing light guide plate and game machine

A display device according to one or more embodiments may include a lightguide plate comprising a transparent part, and an incident surface, the lightguide plate configured to display at least one pattern; and a light source facing the incident surface. The lightguide plate may include a plurality of prisms on a surface of the lightguide plate, the plurality of prisms being arranged along the at least one pattern to reflect light emitted from the light source and entering the lightguide plate through the incident surface out of the lightguide plate through an emission surface of the lightguide plate, and a transparent protective layer covering at least a part of the emission surface, the protective layer having a smaller refractive index than the lightguide plate.

Display device including a protective layer having a diffusion layer and gaming machine having the same

A display device includes a light guide platecapable of displaying a plurality of patterns (-to-) and including an incident surface; a plurality of light sources (-to-) disposed opposite to the incident surface and corresponding to the plurality of patterns; a storageconfigured to store a reference table that represents a relationship between a turn-on state number and a combination of light sources to be turned on among the plurality of light sources for each of a plurality of the turn-on state numbers; and a controllerconfigured to specify the combination of light sources to be turned on by referring to the reference table, the combination corresponding to the turn-on state number included in turn-on control information, and control turn-on and turn-off of each light source according to the combination of the light sources. The light guide plateincludes a plurality of prisms arrayed on one of surfaces of the light guide plate along the plurality of patterns, the plurality of prisms reflecting light toward the other surface of the light guide plate, the light being emitted from a light source corresponding to the pattern and being incident on the light guide plate from the incident surface.

Display device and game machine

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.

Display device, display method and game machine

A display device includes a light guiding panelhaving an incoming surfaceformed on one of side surfaces, a plurality of light sources (-to-) respectively corresponding to a plurality of patterns that can be displayed, and a controllerfor controlling on and off of the plurality of light sources. The light guiding panelhas a first reflective surface () formed on the other side surface of the light guiding panelthe first reflective surface reflecting light emitted from a first light source and entering the light guiding panelthrough the incoming surfaceand changing the propagation direction of the light, and a plurality of prismswhich is formed on one surfaceof the light guiding panel, is oriented toward light emitted from a light source corresponding to the pattern, entering the light guiding panelthrough the incoming surfaceand directed to the pattern, and reflects the light so that the light is emitted through the other surfaceof the light guiding panel.
