  In this example, the configuration of the slot gaming machine 10, which is a gaming machine, is the same as that shown in the conventional example, and a detailed description thereof will be omitted.

  In this example, as shown in FIG. 3, the liquid crystal display panel 14 of the slot game machine 10 is constituted by the liquid crystal display panel 60 according to the present invention. As shown in FIGS. 1 and 2, the liquid crystal display panel 60 includes a liquid crystal display panel surface sheet material 70 on the entire viewer side surface of the liquid crystal display panel 1 including the liquid crystal display unit 2 and the antiglare layer 3. Is attached.

  As shown in FIG. 2, the top sheet material 70 for a liquid crystal display panel has a base sheet 71 of a constant thickness made of a transparent synthetic resin having a flat surface, and a flat surface of the base sheet 71 on the other surface. A transparent adhesive 72 is attached to attach the base sheet 71 to the surface of the liquid crystal display panel 1.

  In this example, the base sheet 71 is made of a synthetic resin having a thickness of about 50 μm, for example, an acrylic resin or a PET (POLYETHYLENETEREPHTHATE) resin. The higher the transparency of the base sheet, the higher the smoothness of the viewer side surface is required.

The adhesive 72 has such a softness that it can fill the concave portions on the surface of the liquid crystal display panel, and has a refractive index substantially equal to the refractive index of the material constituting the surface of the antiglare layer 3 of the liquid crystal display panel 1. Uses resin material. For this reason, the adhesive 72 enters the unevenness 4 of the anti-glare layer 3 and fills the space between the base sheet 71 and the anti-glare layer 3 without gaps.

  In addition, since the refractive index of the adhesive 72 is substantially equal to the refractive index of the antiglare layer 3, the incident light R2 is high without being irregularly reflected at the boundary between the antiglare layer 3 and the adhesive 72 as shown in FIG. The light is transmitted with efficiency, and the display of the internal reels 26L, 26C, 26R is clearly displayed.

In the housing 12, three reels 26L, 26C, 26R are rotatably provided, and a plurality of types of identification information images (not shown) are drawn on the outer peripheral surface thereof. The reels 26L, 26C, 26R face the opening window 16 of the frame 110 described above, and can be visually recognized from outside via the liquid crystal panel 100.

  FIG. 5 is a sectional view showing an example in which the optical shutter according to the present invention is used in the apparatus of FIG. In this example, an optical shutter 120 is used instead of the frame 110, and is disposed on the back side of the liquid crystal panel 100, that is, between the reels 26L, 26C, and 26R.

  The optical shutter 120 changes the state of diffusion and transmission of light when the applied voltage is turned on and off, and is, for example, as disclosed in Japanese Patent Application Laid-Open No. Hei 6-43478. Such an optical shutter uses, for example, a liquid crystal cell (for example, a polymer-dispersed liquid crystal cell or the like) that can exhibit a light diffusion state and a light transmission state in which light is opaque or opaque, and at least the light transmission state. The obtained liquid crystal cell for image display (for example, TN liquid crystal cell, GH liquid crystal cell, etc .: liquid crystal panel 100 in this example) is overlapped, and the liquid crystal cell for image display is arranged on the viewpoint side.

  Note that the light transmission state referred to in this specification refers to a transparent or translucent state in which light is transmitted so that the background can be visually recognized. In addition, the arrangement of the substrate, the drive electrode, and, if necessary, the polarizing plate, the color filter, the retardation film, the protective film (or the protective plate) for protecting the cell, and other cell components are arbitrary.

  As shown in the figure, an AC waveform from a commercial power supply (or a commercial power supply adapter) 140 is converted into a rectangular wave and applied to the optical shutter 120 via an inverter circuit 130. According to the study by the inventors of the present invention, when a rectangular wave is applied rather than applying a voltage having a waveform such as a sine curve or the like, an object behind the reels 26L, 26C, 26R, etc. in a transmission state, although a few percent, The visibility of a landscape or the like is improved, and if the pattern is a pattern or the like, the edge of the pattern is clearly seen or the degree of the pattern becoming dull is reduced, and the pattern is made to look glossy.

  The duty ratio of the rectangular wave formed by the inverter circuit 130 may be, for example, 50%, but may be another value, or may be variable according to the driving state of the device. Known devices may be used for such an inverter circuit and a control circuit. Of course, other circuits and means may be used instead of the inverter circuit.
